Hi there!
I understand what you feel like, I'm not a single mom but my 10 month old was a terrible sleeper, day or night so I'm sure it's even harder for you doing it on your own!
I'll try to make this short; my son is breast fed and he always slept with me. At around 5 months he started waking up more often, like every hour or so, it was so frustrating. At around 6 months I decided to start letting himlearn to fall asleep on his own in his crib and then when I went to bed I would bring him with me. But he still woke up every hour or 2. It didn't make sense to me that at 6 months he would need to feed that often at night so I figured that I must be the reason he is waking, maybe he could smell the milk or maybe I disturbed him when I would move.
I spoke to a couple of pediatricians and a nurse about this and they all told me the same thing, that after 6 months, your infant does not need to feed at night. So, on the advice of a friend, at 7 months I let him sleep the night in his crib and I stopped the night feeds cold turkey! For a week and half he would wake up every 3 hours and cry and I would reassure him. Then one night he just didn't wake up at all until about 6am! I was so happy to finally be able to sleep again!
The other thing was to get him to fall asleep on his own in his crib. I read in a book that the best thing to do was to nurse him until he was about to fall asleep but not to let him fall asleep while nursing. Then you put them in their crib, this way they are very sleepy but they fall asleep in one place and wake up in the same place. It's not as frightening for them when they wake up.
Don't get me wrong, we still have some bad nights, just this last week he started waking up at 3 am! Overall it's been so much better and please don't be intimidated to give up the co-sleeping, it will be better for you and your little one! Good luck!
