I want a reason that involves sleep cycles, or blood sugar, or chemicals or hormones or SOMETHING.
He has a good supper.
He has a nice bath.
He is warm, clean, comfortable.
He is fed to sleep, so has good belly full of milk.
within the hour he wakes up wailing and nothing but another breastfeed will calm him or convince him to go back to sleep.
Once asleep for the second time he often sleeps through until morning, or at least until 11 or midnight.
He is 16 months old.
WHY??? WHY does he wake up so soon after being put to bed? I need a reason.
