Starting to get scared..

I'm 16 weeks pregnant. I'm so happy about this pregnancy, but I'm also nervous and scared. I have another child who is about to turn a year old. I'm worried about how close in age they will be, and I don't want my other child to feel neglected or shoved to the side when the new baby arrives.

I don't regret this pregnancy or wish that it never happened, I love this baby just as much as I love my other child. I'm just extremely nervous. Do any other moms to be have another child that will be close in age with the new baby? My kids will be 17 months apart in age..
