When to tell the kids?

Karen

We had 2 chemical pregnancies in the last six months and this one has given me positive lines for about a week, the others were only positive for about 3 days. My 10 year old has been snooping and has suspicion were expecting but I don’t want to break her little heart if it doesn’t happen. My question is when do you plan to tell your other little ones? I have two DD ages 5 & 10
