OMG -- I'm worried about ending up in the same boat as you with my MIL. She doesn't work, so she has ample time and unfortunately my SIL set a precedence with her "dramatic " recoveries from both her previous deliveries. This has made my MIL think she NEEDS to be present & basically move in for WEEKS with ALL the grandkids. SIL is VERY different from me -- is the type to let MIL give a formula bottle b/c she would rather sleep in the middle of the night than attempt to breastfeed, and has no problem letting MIL do her grocery shopping (I refuse b/c my in-laws are so cheap they would buy crap).
Thankfully, I think MIL got an eye-opener when one of my other SIL's had a baby this past May. She stayed with her a week and came back surprised at how much more efficient SIL # 2 was than SIL #1. Basically, she DIDN'T NEED TO BE THERE 24/7!! Now don't get me wrong, I'm all for someone coming over during the day, folding towels and cooking a caserole, and holding a screaming baby so I can attempt a shower every now and then. But the thought of someone being in my house overnight 24/7 SCARES THE H$LL OUT OF ME! Especially someone who gets on my nerves at family dinners
Seriously, my MIL is a nice lady who raised 6 kids and knows a lot, but she feels like she knows EVERYTHING and I know i'm not going to share her opinions on 100% of the things that I deal with those first few days. (i.e. First thing she said when she saw my nursery setup was "those crib bumpers might kill your baby, you should take them out").
I hate that I'm anticipating the birth of my baby so much, yet dreading stupid things like family interference ruining it. Ugh....all we can do is hope, pray and be thankful they love us I guess.
