So I have an almost 4 month old little boy who was born at 35 weeks and almost died during his delivery. He is perfect now and the light of our lives! My husband and I only tried for a month before we conceived so we were extremely grateful for that. My sister however has been trying for over 3 years and just found out she’s pregnant. I have a beautiful baby so why am I jealous of her? Am I really that selfish? Advice please!
