Well... what do you think would she be better off.. ?

this is awful and this made me sad cause i lost my mother a few month ago to a car crash your mother in law and sister in law are awful people for saying that

Talk to your husband about what you heard them say.

i would say, 'kill them with kindness' but that seems a little heavy-handed in this situation.

Let the games begin

I'd have blatantly walked out and messed wuth the monitor and said it's amazing how these little devices pick up even the smallest of sounds. then looked them in the eye and said any child would be lost without their mother and it'd be horrible to wish that on any child especially baby's name. that remark can be used at any time and it's letting them know that you heard them. bonus if you get hubby to tell them how your child needs you and any more talk of your death isn't allowed in your house etc or around your child

I would tell your husband what they said then tell them they aren't welcome back because you don't want that negativity around your daughter.

Some people are absolutely insane. My sister in law is, and we told her constantly to stop having children because 1) her pregnancies nearly kill her every time and 2) she pawns her kids off on other people to take care of instead of doing it herself (and no, she doesn't work, so it's not me complaining she's sending her kids to day care so she can go to a job. She just legitimately only watches her kids when she can't find someone else to do it for her). We don't know the kind of person or mother OP is, and in my experience people don't just maliciously say someone is better off without a parent for no reason.

Maybe his mother is the one who shouldn't have been the mother in the first place nor her daughter for thinking that of her. As you said we don't know her yet you threw her in the ocean with your brothers deadbeat. Yes they do make them comments, my ex in-laws did and now my ex doesn't live with them either but MY parents. If that's the case hope mom throws the trash out the baby doesn't need judgement by family They'll receive enough from others. But definitely would like a follow up.

I was giving an anecdotal response based on my experiences. People can say all they want that "it's horrible to say something like that!" and have zero basis, and they are so lucky to have no basis, for why someone would WANT to say a child would be better off without the parent who is not really a parent. I was giving my basis of why I've said my nieces and nephews would be better off without said parent and why I don't think people just say "she would be better off without her" for no reason at all.
