I was pregnant when my son was 1 (closer to 2) and had my dd a few months after his second bday. Luckily I had pretty good pregnancies with both so that part wasnt too bad but it was alittle bit of an adjustment having a 2 yr old and a newborn. Honestly though, sometimes I think it was easier then then it is now and they are 10 and 8 lol
I went threw the same thing, its hard but you get the trick of it. My only advice is that even though the one year old won't understand exactly whats going on, let um feel your tummy and let them know there's a baby in there. I didn't do it with my son and then brought my daughter home and we had alot of drama from it.. I got pregnant again shortly after that and my daughter wasn't very old but i explained it to her and him and let them feel the baby kick and it was a completely diffrent story when there little brother came.
