wanting another baby

I need some advice! Since the birth of my premature baby who was born at 30+6 days we haven't had an easy start in life I won't go into detail but she has a lot of health problems! Anyways she's now 2years and 2 months old and I feel ready for another baby but I feel as if I'm being selfish because she has lot of problems with her! Please help me I just want to feel like I can carry a baby full term but also I loved to be in labour! Only ever want 2 children!
