my daughter is 5 months old and was sleeping horribly. she was waking up every hour. exhausting and nerve racking. i was willing to be there for her but i was worried about what so little contniuous sleep was doing to her. she was crabby and tired all day and i read that children need longer blocks of time asleep for their development. then i began some techniques to help her learn how to put herself back to sleep. she's smart and was a quick learner. basically, i was feeding her right before bedtime and letting her fall asleep nursing. so i gradually turned it around by nursing an hour before bedtime and feeding her rice cereal and veggies (she eats most at dinner time) and just comfort suckling at bedtime. each night the suckling got shorter until now she doesn't suckle at all before sleeping. well, last night was the biggest surprise of all... she slept from 8 until 6 in the morning and then she nursed and then slept another 1 1/2 hours!! she's been building up to this waking every few hours and then longer times. i'm willing to get up with her when she needs me and i always do a quick assessment of her condition (feel for fever etc.) but her behavior is all the difference in the world. lately she has been so happy and smiley! i'm not sure how often your son is getting up but if it's frequently you might try some other techniques so he can put himself back to sleep. i really believe that my daughter needed to learn how to do this. now when her light cycle of sleep comes instead of waking up completely and needing to nurse to fall back to sleep, she just drifts off to sleepy by land! ( most of the times i would go to her she would be basically asleep but thinking, i need help to get back to sleep. she wasn't eating very much so i knew she wasn't hungry.) good luck. i too, wondered if her meds were the culpret. it was scary to get started on this but it's worked! good luck, julia
