Just wondering is it the rolling around that's waking him up? It might be hard because its hot.... But when my son started rolling around and waking himself up & was unable to put himself back to sleep I put him in a sleep sack.. It worked to the point where I was only waking up 2-3 times a night vs the 5-6. It wasn't perfect, but for some reason containing those lil legs helped. Even to this day at 20 months he doesn't sleep well unless his sacks on.
Also I should note my son slept right by our bed too (also exclusively bf), and it was right about this point where I found he slept better when I moved him to the other side of the room. I think it helped in that he didn't "smell" me as much and I didn't hear him rolling around as easy either.
Only draw back was I actually had to get out of bed to soothe him when he did wake up. I just put the rocker right by the crib and either nursed or rocked him back to sleep. This also helped me from falling asleep w/ him in bed. Hard the first couple of weeks but I did notice improvemnt. This also began our transition to his own room. Which wasn't fully accomplished until about 11mths old.
I'm sorry I don't have any other suggestions...I was blessed to have a son who loves his binkies and it was at this point where they really came in handy. I've known people who swear by the crying it out method. It didn't work for us so I beared with it & miraculously at 12 mth to the day he started sleepin through the night on his own in his own room. So there is hope...Hopefully some other mom's will have better advice..
Good Luck
