My six month old started sleeping through the night by 2 1/2 months. I count my blessings all the time! However, he had a cold around Christmas and it kind of threw him off his good sleeping habits. Ever since he has been waking up about twice a night making loud groaning noises. He doesn't wake up, but it's enough to wake me up. He is still in a bassinet in our room. Very rarely he will wake up around 6 and want a small bottle. But then goes back to sleep. He usually sleeps about 10pm-8am.View Thread
