loke,
i am in similar situation, tho i'm moving back to mum's. cos my old man can be quite imposing. in fact, he already been like suggesting names for our bb and that's my DAD! and i dun even like it! but of course i'm his princess so i can just tell him not to impose his views on me. but for you its your MIL and very sensitive to say things or how you feel.
i think like you said, the first couple of months may be quite crucial in baby's developments, so maybe just stick to having your mum help you first? then later on, can consider moving to MIL's place.
but at the end of the day, you have to be comfortable with the idea, otherwise your poor HB gonna be the one stuck in the middle. so even if the thot of additional income sounds alluring, i think PEACE is far more priceless in such situations?
i'm lucky cos its my HB who suggested we move back to my mum's so I can be properly cared for. but i'm apprehensive about whether my HB will be comfortable. i mean, of course he's not ngiau and princessy like me lah. but i still have my reservations. because, at the end of the day, its my parents house.
oh, and to make things more complicated, my brother will be getting married, and they gonna be living at mum's as well. at least for the time being, til they find something.
i actually quite like the idea, cos then my bb will have many pple to love. but even my own bro can get my nerves easily. he got nocturnal lifestyle one. last time always have frens come over til like 4-5am in the morning kind. and i, being empress dowager needing peace in the night, ever chase his frens home before. hehe...
so its interesting, got one big happy village peoples! but it can be a killer. so i have to proceed with a lot of care.
is your angel your in-laws' first grandchild? if so, also risk having grandma & grandpa spoil her too much. i think mine will be quite spoilt.
