My MIL would have been very supportive, she was outside her time in that she bf, and took a 5 year career break to raise DH in the mid 80s, ignoring the advice at the time. Unfortunately I never met her in person as she died before DH and I became an item 
My mother however is one of the generation of schedules and "not being taken advantage of. She bf me for a few weeks, but stopped to have her wisdom teeth out.
She was horrified about me planning a home birth, kept ringing me to tell me about how it could go wrong and how would I feel then. She got a bit "I told you so" when I had to transfer for a section (he was stuck, to the point he never engaged correctly, labouring at home actually made the whole thing better, they wouldn't have operated or possibly even admitted me any sooner if I had planned for a hospital birth).
She stayed with me for a few days when I came out of hospital. She was forever telling me to put DS down so he could "get used to his cot" or "learn to be independent". Suggested I gave him a bottle a day when he was a week old to "give yourself a break" (because preparing bottles and cleaning up afterwards is so much easier than sitting on the sofa feeding).
She rang me up to suggest I put him out in the garden in his pram (in October, it was raining) so I could paint the hallway in peace. Told me he needed to cry to "develop his lungs".
I got married when he was 10 weeks old. When I arrived at theirs it was suggested I go up to the bedroom to feed, rather than stay downstairs and talk to my brother who I hadn't seen in years (I stayed down, and my dad came over, talked to the baby and kissed him on the head without realising, even after, I was feeding him). I got a cat's bum face when I told her he would sleep in my bed, and she suggested I put him on the folding bed alongside 
. She was badgering me to give him formula instead of expressing for the bit of the day when he would be with my SIL. I overheard her telling my brothers fiancee "he is spoiled because she never puts him down". All of the wedding day she kept trying to get me to give him to other people (did the walking off jiggling when he was hungry, despite me having made it very clear I wanted to tank him up in the morning when I was getting ready), including my SILs mum, who he (or I) had never met before (my mother invited her, no idea why, but that's another rant). I also got a cat's bum face when I got up from the table during the meal to go feed him (it was a buffet, so no big deal, and I was leaking onto my silk dress).
She still keeps asking me how long he is going, and is appalled that it is actually only 1.5-2 hours in the day, so clearly he needs formula, or weaning (4 1/2 months). She also calls him "greedy" for feeding frequently and "fat" (he is 91st centile, but his dad is 6'2" and built like a rugby player, he isn't meant to be a dainty child).
I try to avoid talking about our daily "routine" with her now, and just tell her about his new achievements instead.
