Dd is 19 months and has never slept through the night ever. She’s in a bed so just gets out and comes into the living room if she doesn’t sleep. Sometimes I have to put her back in bed 30+ times before she will sleep and usually I have to lie with her or breastfeed her to sleep just in order to get a rest. She will get up in the middle of the night and come walking to the bedroom which I find wakes her up completely and then wants to play for hours 😔
I’m on my own with her as OH travels for work and is gone for weeks, sometimes months at a time.
I study full time and have my grades are starting to suffer because I’m so sleep deprived. I honestly just feel like dropping out. I’m so depressed and lonely, every day is just a constant battle to get through because I’m so tired. I have to nap every day because I’m so tired from getting up 6+ times a night.
I have tried gentle sleep training methods but anything that involves leaving her to cry I haven’t been able to bring myself to try because of the dreaded mum guilt
The other night I ended up shutting her door because I found myself getting frustrated after putting her back in bed repeatedly, it was after 10pm and I was just so exhausted. She cried for a minute and then got herself back in bed and went to sleep. She even pulled her blanket back over herself 
My aibu is to ask is this cruel? Do you think she will feel trapped/caged in? She has never slept in a cot and has always had free reign of the house. I wouldn’t let her cry longer than a minute or two because I’m not comfortable with that. Am I damaging her? I just really need to break this habit 
Any tips of night weaning off the breast would also be very appreciated!
