Something has to change

[Shy0717]

To a give a little backstory: I am a single mama to ds (almost 7 months) who works 3 nights a week as a nurse (12 hr shifts). While I'm working I leave him with my parents overnight and pick him up in the mornings. I honestly have no complaint about leaving him whatsoever. My mother treats him of course like her own and is the most gentle, loving and caring grandmother I know. We've battled with ds constant night wakings for some time but we've for the most part just gone with it. For grandma he cosleeps but always wants to comfort suck on a bottle of ebm all night. She started this when he was around 4 months and I told her not to do it because I didn't want it to become an issue later. I know she was just going with what made him happy and what was easier for everyone at the time since having a newborn around completely changed their lives. Fast forward to now....ds is now waking hourly with grandma and refuses all other comfort measures (rocking, patting, shh-ing, paci) until he gets his bottle. She said he throws a full blown temper tantrum. This isn't an issue when its just he and I because he nurses when need be, typically a few minutes, then unlatches and goes back to bed. He does still wake often with me though not every hour. Grandma is on her last leg and would like to come up with some type of plan to help him sleep longer. I also left out that both grandma and grandpa work during the day so they are giving up their nights to help out with the little guy knowing they have to go to work. I'm not worried about him cio because she doesn't believe in that but I also know how hard sleep deprivation is on a person. Grandpa is helpful sometimes but not really all that useful since he enjoys his sleep as well. Needless to say we're now at a crossroads where something has got to change. Grandma is exhausted (as am I but I've grown accustomed to the lack of sleep). I'd love some ideas on how to get ds to stay asleep over there and how to kick this bottle nursing habit. We've had a long discussion about routines and getting one in place with ds so bedtime is predictable no matter which house he happens to be at. Usually my mom just lets him wear himself out then she slings him until he dozes off but I think we need something a little more predictable (as far as timing and such). I'm also going to attempt to get him to start sleeping in his own space. I don't want to give up cosleeping and I know my mom enjoys it as well but honestly I don't see any other way to get him to stay asleep. We also are very realistic about his sleep habits. At this point a 4 hr stretch is about all anyone is hoping for. He has done it numerous times so we know its possible. We just started the sleeping in his crib thing today for nap time and so far its going ok. I have been nursing him then laying him down after he goes to bed with some soft music playing in the background and his little mommy bear noisemaker going (apparently all of that noise is soothing lol). Suggestions would be greatly appreciated.
