DS is 12 months old, just learning to walk and is on a sleep strike! He wakes at 5am, unrested, cranky. Then he won't nap in the morning (just pull himself to stand then start to cry). He crashes at 11am but sometimes only for 1 hour. If I sleep beside him and I notice him stirring, I can get him to go back to sleep by slipping the paci into his mouth. He's always exhausted by 5:30pm too tired to eat a good supper and then I'm putting him to bed at 6:30pm only to start the cycle over again! He's also sleeping much less soundly at night because he cries out several times (which is a new thing). My pediatrician says babies his age always get the sleep they need but clearly DS is very overtired all time and has trouble taking good naps. I should mention, he has always slept alone in his crib for naps and bedtime and is capable of falling asleep on his own the co-sleeping at naptime is something I've tried recently out of sheer desperation to get him to nap longer. I'm frustrated because DH and MIL say I'm fostering a bad sleep habit by co-sleeping, while my mother says "do whatever works". I just want my baby to be well-rested and stop having to go to bed so exhausted at 6:30pm!!! Please any advice???!!!
