How and when did you explain about being pregnant to your other children?
I have two DDs 4.5 and (almost) 3. I'm not sure how to explain to them so that they understand. DD1 was only 18 months when DD2 was born so didn't have a clue what was going on and as far as she remembers, DD2 has always been there. This is going to be a much bigger adjustment for her, and for DD2!
