My little guy is just short of 6mo. I dont expect him to sleep "through the night" but more than 2 hours at a time would be amazing! He falls asleep just fine at night, the problem is staying asleep.
I feel like I have tried so much. I have done white noise, music, a mattress vibration thing to soothe him (all of these things have timers so they are generally off in about 30 min, boooo timers), he has been swaddled, I put him in a sleep sack, he has been put to bed with a passifier and always goes to bed a full tummy (he nurses before bed and has started solid food as well which he usually eats about an hour or so before bed). All these things are great for falling asleep but what will keep him alseep???
