Help with my crazy mom!!

Okay so my son is 3 months old and my mom drives us insane!!! She's still wanting to visit every other day but does nothing while she is here except judge me and make comments!!! She came over yesterday & looked at my baby and wow mom won't put a blanket on you huh, I keep the heat at 73 and he has a full outfit on and socks! He doesn't need to be wrapped in a blanket all day. Or this is my favorite she will say I don't nurse him enough and my milk will dry up (I nurse when he is hungry and pump) he's 17 pounds and gained 9 since birth I think I'm nursing enough! & keep in mind she's never once nursed any of her children! She knows nothing about it! Or yesterday I said want to hold him while I shower, she said ugh I'm on facebook. I felt like saying then go home and sit on favebook! Or if I don't get the laundry folded and put away as soon as it comes back out I need to wash it again...wtf?! So annoyed with all the little comments she has to say and I don't know how to tell her that she needs to space out the days she's coming, I can't deal wth her here every other day but I don't have the heart to tell her that. What should I do?!
