Brendan Cooper's Timeline (Big Toddler Ella's Brother)Added:
[music] [music] [music] >> Brendan Cooper was born in a hospital on July 20th, 2008. He had a father named Ethan Cooper and a mother named Martha Cooper. His father worked at a car dealership. Brendan also had an older sister named Ella Cooper, also famously known as Big Toddler Ella.
Everyone was happy about Brendan's new arrival to the world, except Ella. She wasn't too happy about that because she wanted a sister instead of a brother.
>> Oh, Martha, Brendan is such a cute and beautiful baby boy. He looks just like me when I was a baby.
You are such an additionally sweet bundle of joy, Brendan. You mean a lot to me. Hey, Ella, would you like to hold your little baby brother?
>> I'd love to, Dad, but I would rather prefer to have a little baby sister instead of a brother. I want to have a little princess who is just like me.
>> Okay, Ella, suit yourself.
>> Having a baby brother is stupid. I still want a baby sister so badly.
>> Cut it out, great. Now, Ella, you should be grateful of what we have. Even if you have a brother, you are still a big sister. We have what we have, and that's final.
>> I want a baby sister, or I want a sister. I want a sister. I want a sister. I want a sister. I want a sister. I want a sister. I want a sister. I want a sister. I want a sister. I >> That's it, Ella. You're grounded when we get discharged from the hospital.
>> Get up from the floor now, Ella.
>> Brendan's father was angry at Ella. That was where the sibling rivalry all began.
When the family drove back home from the hospital, Brendan's parents grounded Ella for her misbehavior.
>> Go to your room now, Ella, and think about what you said about Brendan.
>> Whatever, I still want a sister anyways.
>> Despite Ella's despicable behavior, Brendan's parents loved him very much.
In 2009, 1 year later, it was Brendan's first birthday. The whole family was happy to gather to celebrate, except Ella. Ella was still jealous about Brendan.
>> Happy first birthday, Brendan. Would you like me to help you to blow out the candle?
>> Ooh, I will help Brendan to blow it out.
>> That's very thoughtful of you, Ella.
>> Unhappy first birthday, Brendan.
>> Woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, woah, Ella. How dare you to wish Brendan an unhappy birthday? That was very disrespectful of you to do that.
Get to your room now. You are grounded.
No cake for you.
>> The sibling rivalry still continued on.
In the year of 2011, when Brendan grew older to be 3 years old, he loved catching butterflies with his net in the backyard. Brendan noticed a praying mantis clinging on the white daisy. He thought it was an interesting-looking insect. He decided to put it inside his net and take it inside the house.
When he took the praying mantis inside the house to the living room, Ella got scared. She hated the praying mantis.
>> Oh my god, Brendan. You get that vile scary-looking praying mantis away from me.
>> Ella, it's just a praying mantis. It won't hurt you.
>> But I hate that praying mantis. Get it away from me.
>> Ella, what's going on?
>> Brendan is scaring me with a real praying mantis in his net.
>> Brendan, you take that praying mantis back outside. It doesn't belong in the house. You don't scare your sister like that.
>> Okay, fine. I'm taking it outside. My sister is such a wuss.
>> Hey, you take it back. I'm not a wuss.
I'm a princess.
>> Yes, you are. You get scared of every little thing.
>> No, you are.
>> No, you >> I'm not.
>> Yes, you are, Ella. You're such a big crybaby.
>> Brendan, Ella, that is enough.
Both of you.
Brendan, take that mantis outside or you're grounded. Ella, pick up your dolls and castle play set or you're grounded as well.
>> The sibling rivalry had gotten worse as Ella and Brendan kept fighting.
In the year of 2018, when Brendan got older by the age of 10, Brendan and his father went outside to the pond in the front yard to feed the goldfish.
>> It's nicer and quieter to be out with you, Dad, without Ella around, especially when feeding the goldfish in the pond. I don't like her much. She's such a big pain.
>> Ella is your sister and she always will be.
>> She's such a woman child. She acts like a big toddler and has an obsession of fairy tales. She always picks fights with me all the time. She is the worst sister I've ever had.
>> Well, Brendan, you pick fights with your sister, too. You're not the only one who have a sibling rivalry. I, too, have a younger brother named Oliver. When Oliver and I were young, he used to be annoying to me when he wanted to play lightsaber challenges with me. I sometimes got angry or annoyed by him.
That doesn't mean that I hate him. I love them and care for him as a brother.
>> You think I should give Ella another chance? You think things will work out well between me and her?
>> Brendan, I'm sure you and Ella will get over it and the sibling rivalry will end soon. I'm sure you both will get along with each other better. You're both growing up.
>> Brendan decided to give Ella another chance and how to be a better brother to her and get along with each other well.
In 2022, when Brendan was a newly high school freshman at the age of 14, things did not go so well. He was humiliated by his classmates.
>> Oh my god, you must be Brendan. I have heard a lot about your older sister, Ella, or shall I say big toddler Ella.
Your sister is such an overgrown toddler-like woman-child.
>> Oh yeah, I have heard about her. This is such an embarrassment to have a sibling who acts very childish.
>> Poor Brendan felt heartbroken, embarrassed, and left out after his classmates shamed him for having an older sister who acted like a toddler.
He had no one to be around with him at school with everyone gossiping about him and his childish older sister.
In 2025, when Brendan was 17 and in the senior year of high school, Brendan wanted to do something nice to his older sister Ella.
>> Hey Ella, want me to go to the toy store to get whatever you want. I am giving you a special treat.
>> Oh yes, Brendan. Zip-A-Dee-Doo-Dah.
Let's go there.
>> Awesome. Let's go.
>> When they arrived at the nearby toy store, Ella wanted to ride on unicorn kitty ride instead of looking for Barbie dolls or unicorn stuffed toys.
>> Ooh, I want to ride on the unicorn kiddie ride.
>> Ella, I thought we were looking for unicorn stuffed toys and Barbie dolls you wanted.
>> This unicorn kiddie ride will make me ride through the enchanted forest and make me feel more like a princess.
>> Ella, that ride is designed for smaller children. You are too big to ride on it.
I don't think you will fit on it.
>> Oh, shut up, you You can't tell me what to do.
>> I'm not telling you what to do. I'm just saying that you will not fit on there.
>> Just let me ride on the unicorn kiddie ride.
>> Ella, you are acting very childish. Stop it right now, or we're leaving.
Ella, I have had it.
Get up from the floor now. We're leaving. You get nothing.
Ugh, this is such a disappointed and an embarrassment.
>> [cheering] >> In 2026, Brendan finally graduated from high school. He was the class of 2026.
His family was very proud of him as they cheered and applauded for him. Brendan noticed how well-behaved Ella was during his graduation ceremony.
Brendan and Ella were now getting along with each other quite well and were no longer fighting with each other after the years they got older. Brendan still loved and cared for Ella as a caring, thoughtful, devoted little brother. He was thankful for his parents, especially his father who gave him advice of how to be a better brother. Brendan was still an important part of the family as he gave a helping hand to care for his sister Ella. Though she still acted very childish like a big overgrown toddler.
>> I want Disney princess diapers.
>> Oh, brother. Here we go again.
>> [applause]
