I'm loosing hair too!
Jay- E recently seemed to totally regress with his sleep. Naps are down to 45 mins max and he was a mess in the night. We decided to try to move his bed time forward, and now he is in his own room (amazing) and sleeping a little better but back to waking every 3 hrs. Maybe it's the 4 month sleep regression (which we think is our culprit). I also have had success with using a rolled towel under his legs to help with tummy cramps as we can't use infants friend anymore (had a skin reaction). Hope u get some relief soon!!!
