Mommas! Opinions please. So my situation is this: my significant other and I are expecting our babe in April. I have 2 kiddos from a previous marriage and he a daughter from a previous relationship. All 3 kiddos will be home (with us) for Christmas. We should find out for sure Dec 4 the sex of the baby. I was thinking of us keeping it to ourselves and wrapping a box for all the kids with "big sister" & "big brother" shirts and then "little sister or brother" in there too to surprise and tell all 3 kids together what their sibling is. Then take a photo of the kids in their shirts holding the babies shirt to share with our friends & family. Cheesy? Cute?
