my baby will turn 4 months in a couple of days, he is formula fed, a couple of weeks ago he established a great night routine, he would sleep at 7pm, wake up at 12 am, feed, go back to sleep till 5 am, feed, then sleep till 7 or 8 am, then he had a cold that messed up his sleep, he would wake up every hour or so crying, after the cold went away he still woke up every hour, i tried feeding him but he wasn't hungry, for the last 3 days, he would sleep at 9pm, wake up at 1 crying (not hungry) slept and woke up at 5 am crying but also not hungry, i would love it if he would sleep through the night, coz it seems he does not need night feedings anymore
