I think you have to accept it, OP, hurtful or not. They may change their minds after the baby’s actually arrived,
COVID aside, I really don’t understand this ‘no visitors for a month while we bond’ business, but judging from MN, it seems pretty common now. Or should that be ‘fashionable’?
Personally I was only too pleased to show off my new babies to family and friends, and dd has been the same with her 3. We first met all of them within hours, and she was always happy for anyone else to enjoy a cuddle.
I dare say there can be problems with the sort of people who stay too long and expect to be waited on, so if parents or in laws etc. are that type I can well understand it.
IMO visitors in the early days should come prepared to muck in, put the washing on, hang it up, or do anything else that clearly needs doing, and preferably bring a meal that can just be shoved in the oven to heat up later.
As far as I could tell, all dd’s friends were the ‘bring a meal and muck in’ types.
