Is it normal to feel annoyed or jealous?

I get annoyed or jealous sometimes when people talk to me about their preemie's who were born at 36 to 37 weeks. I know it's also not a great situation for them and also quite stressful but to me that seems like a good deal compared to having a child born at 29 weeks and having numerous health issues from it. My nicu neighbor's baby was born at 37 weeks and I can't help but feel jealous
