My son is 6mths and he has been sleeping through the night since he was two months old.  He is in bed anywhere between 7 and 7:30 every night until around 7-8am. 

Ever since the time change he has been struggling with sleep.  His normal 5pm 25nap turns into hours and hours and he misses the normal last bottle before bed.  He'll wake up at 1am and want to eat then. He also wakea up alot more crying now which he has never done before. Ive tried letting him sleep when he wants but its all over the place and hes skipping his normal meal times. Its almost like we are dealing with a one month old again!  Help, this momma is tired!  Hes been sleep trained for months why is he regresssing?
