#3 (tiebreaker) is due 2/27/23!!

My husband and I tried for 3+ years for our third baby. We had 6 losses and now I finally made it to 7 weeks!!! How long would y’all wait to tell your kids? My son turned 9 in April and My daughter turns 5 in august and I’ll be 12 weeks around her birthday. We thought about waiting till then but I want my kids to be the first to know. I already feel like I’m showing a little. My mom and husband and bestie and cousin(like a sister) are the only ones who know. I want to share this exciting new but I’m also scared of losing this baby again. I have an ultrasound tomorrow and kinda of want to tell me kids then. If it all works out at least. Any tips?
