Family issues during pregnancy

Hello. Does anyone else have a similar issue or an opinion on what to do. I am currently 4mo pregnant and my mother in law keeps saying how after the baby is born she wants to come stay at our house for a month or two. I completely understand she's coming from a good place to help out. But I honestly don't think I want anyone here after, specially for that long. I want that time to bond with my baby and my husband alone. Also I feel like already everyone since they have kids want to keep telling me what to do and how to do it. I like the opinions once in a while and the help, but I don't need it here 24/7. How do you think is a nice way to tell her without hurting her feelings? I just feel either way I say it it's not going to come off in a nice way.
