Baby # 3

My husband and I gave been throwing around the idea of having another baby. We currently have 2 boys. 3 and almost 1.5. I always wanted my babies 2 years apart. So it is time to try. I just flip flop. I love my two little boys so much and don't want to stress anymore than I am. But then I want another baby so bad as does my husband. So conflicted any advice on making a decision?
