Having a child is the most amazing and wonderful thing in the world. After all, you carried this child for 9 months and anxiously waited for him/her to make their grand entrance into your world and everything is all dreamy and wonderful. Then you enter into the sleepless nights of midnight feedings, diaper changes, singing, coddling, rocking, swaying, etc. and then you wonder when will you get a full night of sleep again? Well the answer is sooner than you think! Just to lay it out there - I'm not a sleep expert nor do I claim to be one. But I do have experience from sleep training our 3 children and I can happily say that my husband and I have peace and quiet from 8pm on and we sleep through the night (minus sicknesses/teething issues/nightmares/etc.) because we have successfully sleep trained our children. So back to my point... Initially, infants don't have the internal mechanism to put themselves to sleep or even to know day from night....
