MIL too interfering..

Sma

We are expecting our first child in July and my mother in law and father in law want to be there during the childbirth ..I understand it's really thoughtful for her to say that but then they want to stay with us for another 6-7 months after the baby is born ..I don't want them to come and I told my husband that we can manage all alone ..I don't have a really good relationship with my MIL coz all she have done is interfere in my relationship and she want eveything to be done her way.. long story short is it really difficult to manage alone with the baby?????
