My oldest son turns 12 today and I'm 12 weeks pregnant today. (We also have 9 year old G/B twins.)

I'm kind of worried about the age gap. I know the kids will be happy when we tell then, especially my daughter whose been dropping "I want a sister" bombs for over a year now. Lol. (Were telling them on the 18th after my next ultrasound appt) but anyhow, if anyone has kids who has a big age gap, please share your experience. I don't even know what exactly I'm nervous about. Im just nervous, anxious, a little worried and I can't help it.
