Mommas with bad sleepers… when did your baby finally start sleeping through the night? My 1st was a great sleeper from day 1 she slept 4 hours at a time then would sleep through the night by 2 months. My 2nd baby is a horrible sleeper. She is almost 7 months old and still wakes up anywhere between 3-8 times a night. We go to bed around 8, she only takes like 2 naps during the day. She is fed before bed so she has a full belly… how much longer till a momma can get a full night of sleep!
