It's Abby's Advice, where I get letters from friends

and try to help them solve a problem.

- Dear Abby, I'm excited to be a big brother,

but what does a good big brother do?

Signed, Soon to be Sibling.

- Well, I know about being a big sister

because I have a brother named Rudy.

It's a lot of fun to have a sibling.

You can read books to them.

- And they lived happily ever after.

- Sing songs with them.

♪ Do do do do do do ♪

- And play games like peek-a-boo with them.

- Peek-a-boo.

(baby giggles)

- There's so many things you could do together.

- I can do all those things.

I can't wait to show my new baby sister all my toys.

- You're gonna be a great big brother.

Can't wait 'til I get another letter.

(laughs)

Twinkle out.
