Yes, both my Lo's slept for at least four weeks. WE didn't get into EASY until about 4-6 weeks and it was a gradual thing. AT 16 weeks my DD is taking great naps (usually) and sleeping from 10-6am at night...so waiting the few weeks wont hurt. It is fine to relax, enjoy your baby and build your milk supply now by feeding more often so that in a few weeks you can start some simple routines. I regret with my DS#1 that I didn't relax more the first few weeks. I was too concerned with getting him into a routine and it was really too early because he couldn't stay awake longer than a few minutes. Just enjoy your little one and get some sleep while he sleeps!
