First of all sneaky mum and dad give them both a clue, a picture of a baby scan, and ask them what they think it could be.
They don’t know, and the best part is that they have absolutely no idea what their parents are about to tell them.
When dad tells them, they’re both speechless with huge grins. But it’s not long before the little girl finds her tongue and gives possible the best reaction we’ve ever heard: “You’re having a baby in your tummy right now?” Cute and funny.
The little girl can’t contain her excitement and runs up to hug her mum, wailing with joy. The little boy seems to take a bit longer to process what is actually happening.
But it’s not long before he joins mum and sister (and bump) for a group hug. Mum then proudly shows her bump off to her very excited children, before the little girl says: “I can’t thank you enough.”
