Opinions on visitors after section...

Claire
Guys I need opinions. I'm scheduled for my section this Tuesday 8th November. I'm a FTM and can't wait to meet my little boy. The only visitors I was expecting in the first day were my mum, sister & brother. And my partners mum, dad and his sister if she wanted to. However my partner informs me today that his mother said that if we get took early on Tuesday and people can come to the afternoon visiting then her and her daughter will come (as my partners dad won't be finished work yet) and they will also have to bring my partners sisters 18 month old son as there will be no-one else to watch him until later on in the day. I have no desire for my partners nephew to visit me on the first day let alone at the afternoon visiting as no doubt all the focus and attention would land on him as usual and the attention would be taken away from our baby. Unreasonable?
