No way! You’re no contact for a reason. Anyone no contact with me does not see my child. They will poison your child against you.
They can meet the baby when you are comfortable with being separated from your child
You say another baby - what happens with your other child? Do they see your MIL & SIL?? I would not make any promises or plans yet. Wait until after the baby is born and you see how they are feeding sleeping, how you are etc - otherwise it could possibly end up used against you if you make a plan/agreement now and it doesn't happen. You don't say why you are no contact just that your husband is so it's hard to say if they ever should be around them.
I feel like asking the baby to spend any time away from you until it is on a more established feeding schedule is a no go (this obviously applies to breast-feeding) but if you are not leaving the baby to go to work, you should not be expected to have the baby taken from you to go be with people you don’t speak to. If your husband still has a relationship with them, it is harder to say that the baby cannot have contact. But that is something the two of you will have to talk out, and you’re the one going through labor and birth not your mother-in-law and sister-in-law. So you get to have more control than they do. And if your husband pushes for it too early,that is a huge red flag.
