Well said @MzHz.
I feel so sorry for these new mothers being so imposed upon.
I have NEVER heard of it in real life.
NEVER.
Only on batshit MN threads like this do you have new mothers having to deal with entitled parents demanding "their go off" their baby like its some toy.
Grandparents, good, bad, indifferent, have zero entitlement to spend one on one time with ANY grandchild unless the babys MOTHER is 100% happy with this decision.
NOT the father.
The babys mother, that carried and delivered the baby, gets to decide if she is happy for her new baby to be away from her.
I cannot imagine what type of people think they have some right to think they can demand the sole use of a 4 month old at a specific time and cause drama because they are told no, ....actually, the parents have no wish, need, desire to have their baby to be away from them.
I can honestly say if me or any of my friends had come across this in any shape or form it would have been so brutally and finally shut down.
Fortunately like I wrote, I have simply NEVER heard of this.
Its completely batshit.
