DD and I moved in with my parents last year when I left my XH and he started making threats. The plan was for me to move close to XH, so that kid exchange could be easier, but then he started becoming insecure and thought making threats would help his cause.
Anyhow, we've lived here, in the house that I lived in from the age of 16 to 25, for over a year now. It's a "single-family home", with 3 floors and 3 bedrooms...located in a really family-friendly neighborhood with a great little park walking distance. This was only supposed to be a temporary measure, but then it suddenly dawned on me that it would be a huge advantage to stay longer, so I could wipe out the debts XH had put in my name and save up money. Also, as DD adjusted to her new surroundings, she became hugely attached to my parents. I feel it would be cruel to yank her away from them now that she identifies them as her family. Finally, I feel that by staying here, I am giving DD a slice of the childhood that I could never afford to offer her on my own.
Overall, I feel that the arrangement has worked very well for all of us, perhaps because we were close to begin with. Though there were some serious bumps between us when I was married to my abusive alkie XH, my parents and I are very close. My father is generally ecstatic about my being here, as he feels it is his duty to help his only child get back on her feet. The whole "multi-generational living" thing is also very near and dear to his traditional Viet values. Most of my extended Asian family lives in similar types of arrangements.... He did however insist that I pay for 1/3 of the food and 1/2 the gas (since my parents use their cars to drive DD to and from daycare), because he fears that I'll just become lax about money. My mother is way more easy going, and she feels that since they are using certain services anyway, there's no need for me to pay. I still do though.
My father is semi-retired, so it's very helpful to have him at home most days. He does laundry, lots of cleaning and occasional grocery shopping and cooking. My mother does most of the cooking and groceries, and works full-time. I work the longest hours so my chores are generally tidying/cleaning, laundry when I can, and contributing yummy deserts and breakfasts here and there. Since DD's tdaycare is close to my mother's work, we both take DD together in her car every morning, and then drive over to her work which is right next to the subway. I travel to my work from there by subway. Usually my mom and dad swap who goes to get DD, usually at 4:30. Since I finish at 5:00 and work downtown, this is a HUGE advantage for DD who spends less time in daycare.
In terms of child-rearing, we've had lengthy discussions about what I want and how I would like them to intervene where DD is concerned. My mother has asked me on numerous occasions if I felt she overstepped her bounds when she disciplines DD, and I really appreciate that. Whenever DD displays a new kind of behaviour, we'll all discuss our approach together, which I think is awesome. However, I feel that now that things are settled into a routine, my parents step back way more and let me handle DD. I know they don't agree with all the things I did parenting wise (extended bfing, cosleeping, etc) but they just agreed to let me do my thing.
In the end, DD gets LOTS of love and attention. Her language skills are doing awesome with the added input of daycare AND three adults at home. I get to have a tiny bit of a personal life since my parents watch DD after I put her down if I ask them. There isn't much privacy though, and I've been blessed to meet a *very* family oriented and tolerant bf.
The long-term plan that's coming next year or so is for my parents to sell this house and to purchase a duplex with me. They'd live on the main floor and DD and I would live upstairs. Ideally, we'd find a place that has an internal stairwell so that DD can easily travel between apartments. This way, we'd all regain some privacy but still be close....because we enjoy being close.
