Cutest sibling reactions to baby.

British boy finds out he's going to be a big brother- This seriously might be the cutest thing you ever watch.

Brother sings to baby sister- He sings to her, "You are so beautiful to me" and it's so sweet.

Big brother cuddles with little brother- He doesn't want to let go.

(This is not a pregnancy announcement, they are just so cute! I hope Norah adores her siblings one day.)
