Just a few questions to ponder:
You say they are skilled cooks/cleaners. Will they:
- Actually plan on cooking/cleaning or want to play pass the baby all day when they stay?
- Will they need assistance getting everything together (i.e., will you need to take them food shopping, or do more work than just letting them know where your spice drawer, pantry and fridge are?
- Will their idea of cleaning be rearranging your sock drawer or any other location previously arranged to your liking that will need to be fixed after they leave, or give you a hard time locating items during their stay?
There's a bit of a language barrier:
- Can you communicate with each other well enough that you can easily ask for help (like a glass of water or a snack while nursing?)
- If they plan on helping without needing prompting from you, will you know what they plan on doing (like rearranging your sock drawer)?
- Will you have a lot of awkward silences because of lack of communication that will make you all uncomfortable?
- Do they know you and your personality well enough to know if you're being a little snippy because of PP issues and not take offense?
A few other things to consider:
- Will you be comfortable nursing in front of/around them?
- How much time will your husband be able to spend at home with you all? If not much, will he plan activities/itineraries for your ILs so you get a day (or even a half day) here and there to yourself? Would your ILs be comfortable doing a little touring by themselves?
My own experience - my ILs were a great help. My SIL came and helped with nursing (plus I wasn't comfortable being along yet), and my FIL & MIL came and helped out (doing laundry, cleaning out the extra fridge, taking me to PP doctor appointments). Plus, I had no fear nursing in front of my FIL. Well, I had no fear nursing in front of anybody in my home, but that's me and my comfort level with my ILs. I don't think they asked once whether they could hold my son.
My family, though, I didn't invite over much. I find them stressful, and more inclined to want to play pass the baby, so I kept them away. They were butt-hurt, but too bad. It's what I needed to survive the post-partum period.
If you are concerned with your support system, you could look into hiring a post partum doula. They do light housework, and help with baby stuff (like nursing issues - many are certified breastfeeding counselors). DONA's website has a search function that you could use to look up doulas in your area, and you could ask your OB/Midwife for recommendations.
In my opinion, the main things you need are 1) Freezer meals and snacks 2) A huge water bottle 3) 1 support person to help you out during the day and 4) The phone # to a lactation consultant and a list of breastfeeding support meetings in your area. That's until you get the hang of BFing (took me 2 weeks). I found that once I got that figured out, most of everything else fell into place.
