waking up a million times a night

Katie
Anyone's 4 month old still waking up a million times a night? We cosleep so normally I just pop my boob back in his mouth and he's happy and falls asleep so it wasn't a huge deal lol. But lately he wakes up screaming and it's really difficult to get him to go back to sleep. I think he might be going through some sleep regression. I keep seeing stories of babies sleeping through the night and I'm like aahhhh jealous. (We've tried getting him to sleep on his own like every day for 2 months but it wasn't working out, that's why we cosleep)
