hi, my 8.5 month old son has been waking during the night for a couple of months now. some weeks are good but lately he has been terrible. he can wake so many times in a night a some nights he is awake for 2 hours as he can't self settle. he has also started rolling onto his tummy in his sleep but doesn't like it so that wakes him a lot too. he has only had both his arms out of his sleep cocoon for about a week now. i did controlled crying with my daughter when she was 10 months old and by night 4 she was self settling and sleeping through the night so i want to try the same method with my son (she was also crawling when i did it and he isn't) but as he is cutting his top 4 teeth slowly at the moment and only just being arm free i am not sure if i should attempt it or not or if i should wait another month???? any opinions? is there ever a good or bad time to do it?? some nights i have had enough of getting out of bed that i put him in his swing just so i can get a few solid hours. bad habit i know.
