I think a lot of people missed the point on this, tensmum. I didn't take it to mean that pushy mil was insisting on coming to stay for days and days butting in and causing trouble. The op basically asked whether it was unreasonable to get her dh to ask his mother to wait a week before any visit to see the baby. I think she said they live an hour away, so there would be no need to stay, and take up hours of their time.
No one who thinks it's perfectly reasonable to tell mils to keep away has put what I would say is a compelling argument. It's all been the usual moans regarding mils. Mine is no exception, she does things that I've asked her not to, passes comment when really there's no need to, she's the queen of forgetting birthdays and manages to make me feel like the worst mother or wife in the world on occasion. But she does love us, and we love her, you can't change the way someone is, and I don't think she means to do it. I know when my mum has been a pita, it still smarts a bit if dh makes a comment, so I can understand the unconditional love he has for his mum. Besides, I'm not perfect, I'm sure I've said or done silly things that could be misconstrued over the years. I'm not saying we should all lay down and take everything mils throw at us, but i can't help feeling that sometimes we're too quick to take offence.
The thought of my mil coming to stay for ages in the early days brings me out in a rash (particularly as I lived with her when ds was first born!) but to get dh to tell his own mum she's not welcome in the early days is unkind, and smacks of getting him to pass some kind of silly loyalty test.
Anyway it doesn't really matter because I can see allnew decided not to ban her mil from seeing new baby anyway, so apologies for wittering on about has she asked her dh etc. in earlier posts.
As the mother of a son, I don't expect to have a right to see any grandchildren I might have, but of course I would want to see them as soon as I could without imposing myself on any future dil.
