Re: 8 month old waking every hour or two at night
Mine was the same. You can try ibuprofen for teething. That can help a little bit. For the most part, though, you just have to wait it out. Mine started getting better around 10 months. He still wakes at night, but it is not nearly so bad.
I could not bed share with my son from 6-8 months due to an injury; so I had his crib placed next to my bed. It might help some if you can do that. You each still have your own sleep space, but you don't have to get out of bed to tend to him.
