Hi S.,
I am a mom or 4, with my youngest being 4 months. Yes, a child that age is perfectly capable of sleeping through the night. It is entirely possible to sleep train a child as early as 7 weeks old. I have fed and napped 3 of my 4 kids on a schedule and they all slept through the night by 8 weeks. This last one was a little slower on the up take, but she was sleeping through by 3.5 months. By sleeping through, I mean I feed her at 9:30/10:00 and she sleeps until 6:30am. The last 2 have been exclusively breast fed until 7-8 months (it's just my preference to start solids later, rather than sooner) and this one will be as well. The key is to make sure they are getting enough sleep overall (at this age, 14-16 hours in a 24 hour period) and that they are getting plenty of daytime sleep. Sleep begets sleep. The schedule way has been so much better for us than the demand way. I did my first like that and it was a nightmare compared to the schedule way. Love it and would NEVER do it any differently. Oh, and 3 of the 4 have also slept in the crib from the moment they came home from the hospital. They have done great! Two of them shared a room as babies with an older sibling and they still sleep very well, even with the potential for disruption. We've had my older daughter have a nightmare (or need a drink of water!)and wake up crying and the baby just sleeps on...hope this helps! Blessings to you!
