I had a similar experience to Karina, it end in me telling MIL where to go in not a very nice fashion, but she was coming out with the most horrendous (verging on dangerous) advice.

If you are already feeling like you don't want help in those first few weeks, then don't have any. That is how I felt, but I was talked into receiving it and it was the worst mistake I have made as a parent so far. Basically if the help comes with baggage then you are better of without it. Saying that though if you know there are those that can help in a nice, unobtrusive way then certainly accept it.

Maybe to make things easier on yourself, why not hire a cleaner for a month so you have less to worry about and have more baby bonding time. It is such a special time, make the most of it.
