Once baby has been born is there set visiting times on the hospital? And can I get a say on who and when people can visit us?

I get on really well with the mother in law however she seems to think that as soon as he is born she is going to come in the room.

At the end of the day I'm the new mum here and I'll have just push a baby out. In my eyes I want to make sure he's .clean fed and settled as well as important mummy and daddy baby bonding time before anyone comes in. I won't feel comfortable with that sort of stress straight away or even having to deal with in laws. Plus it.might not be a straight forward birth.

am I being selfish??
