Having 1 child

Hello Everyone,

So I have a question is it selfish to have just one child? I have a 4 month old and I decided that I just want to stick with him. The reason I’m deciding not to have another child is because I’m scared of having complications during my next pregnancy. Labor puts you so close to life or death sometimes and I’ve been having serious anxiety about that. Is that selfish, because a family member told me that’s selfish of me and I should at least have 1 more child so my son will have someone to grow up with.
