Baby number two is on the way for Coco Rocha! The 29-year-old model made the announcement on social media with a little help from her two-year-old daughter, Ioni Conran, and the video is guaranteed to put a smile on your face.

鈥淵our attention please! @ioniconran has a very important announcement to make!!鈥 Rocha captioned the video, in which she stands looking glam in a black ball gown and holding her tummy, as her excited toddler pops out from behind her to let everyone know she鈥檚 going to be a big sister.

鈥淪urprise! There鈥檚 a baby in mommy鈥檚 tummy!鈥 little Ioni excitedly yells. Based on the crib and stuffed animals surrounding them, the two appear to have made the announcement from the new baby鈥檚 nursery in Rocha and husband James Conran鈥檚 famously colorful home.

Ioni鈥檚 own popular Instagram account also posted the announcement with a slightly different video and the too-cute caption, 鈥淏ig sister alert!鈥

Recently, fellow model Chrissy Teigen also enlisted the help of her 18-month-old daughter Luna to reveal that she and husband John Legend are expecting their second child, too. The adorable video featured the big-sister-to-be pointing at her mom鈥檚 tummy and saying, 鈥淏aby!鈥

While we鈥檙e all for an over-the-top Beyonc茅 photo shoot or a glam Speidi maternity shoot, the trend of having toddlers revealing the news for expectant moms is one we can get behind. Congrats to the growing Rocha and Conran family!

What do you think of little Ioni鈥檚 adorable announcement? Let us know @BritandCo!
