I personally don't know if you will regret not seeing the baby, I don't think anyone can tell you that for sure, they are not you. But my friend hasn't regretted it.
They tried to make her look at her son(sb 25 weeks), but she refused & she doesn't think she could've coped if she did see him.
As I said before, 20 years later she doesn't regret that decision. I don't think she named him either. Although if its past 20 weeks you are supposed to as they need a death certificate. I'll have to ask her if she had to or not.
If you choose not to see your baby, thats your choice & don't let anyone make you feel bad or guilty for that decision.
