I feel I have to come back and post on this again, because it has buzzed around my head all night.
People declaring lunacy and silliness in modern parenting - shame on you. I thought mumsnet was supposed to be somewhere we could raise other mothers up. It's her baby. If she doesn't want people slobbering over it then she should be allowed to say. Is a sign a bit blunt and clumsy? Yes. But now you know how she feels, so good for her.
I spent the first three years of my sons life sat next to him in hospitals, often intensive care, often on a ventilator. He was very small and very sick, and sadly even nice relatives are often dicks about wanting to cuddle a baby. "I won't stay long, I've got a stinker".... "Just a quick cuddle because I think I'm coming down with something".... "To be fair I felt like shit when I visited last week, but couldn't miss the chance for a cuddle'" I have heard every line.
At times I wasn't even "allowed" to hold him myself because even handling was deemed by the nurses to be exhausting for him.
That was more than 20 years ago, and despite me making a weak attempt to shield him from people who selfishly wanted a cuddle, he has grown up to have good relationships with his family.
We were lucky that he survived, many kids like him did not, and there was no obvious reason, no genetics, nothing to indicate why he was the one who got so sick. It was only when he was much older that they discovered he had no discernable immune system to respond to anything. Great Auntie Nora with a questionable cold sore brewing can't see whether a three week old has a good enough immine system when she lunges in for a cuddle....
This narrative about it being good for the baby.... its good for the newborn to be held by its mother, not every member of the family including snotty uncle Frank who always has huge boogers hanging out of his nose.
This is just the first few precious weeks, and she is full of hormones, probably has sore tits, and still needs to pee while holding a shower head pointed at her fanny...
Give her a break!
I have no doubt that when this kid is bringing home weekly snot and various other "infestations" from nursery and school you will be able to cuddle as much as you like, and the kid will be at a stage where they are able to build relationships, and return your snotty favours from when they were a newborn and you gave them a gift you didn't even know you were brewing.
We need to be more supportive of new mums at this time. It's emotional and exhausting and if she wants you to give space, then give it. I wish people had given it to me.
