DS was born at 27 weeks. I've worried lately that he's not sleeping enough 'cause he still wakes up in the night 2-3 times to eat and only takes 2 short (an hour each) naps a day, one in the morning and one in the evening. Around a week ago he started sleeping almost every night from around 11 to about 6-7 a.m. which I LOVE, but along with sleeping more at night, he's now taking longer naps in the morning and evening and an extra nap in the middle of the day. He's 4 1/2 months corrected age. Is he sleeping TOO much now or is he finally at the right amount of sleep? Just wanna make sure if I should be keeping him up through one of the naptimes or not. Thanks!!
