Hello! Do you think there's an ideal age gap between children? I'd like to hear everyone's opinion. I'm actually confused, some say have a baby right away, it's great weather for that. But what about me? I just got out of the hospital, should I go back already? Some say it's not necessary, it will be difficult, and firstborns always get jealous of other kids, I know from experience.
