Well you have to follow your LO , at first i didn't do a schedule per se, i only tried to keep to the order of things, ex: i never left him eat to sleep, and to wake him if he got asleep during a feeding i would change his diaper, and that's pretty much it. when he was that little i never woke him during naps, he woke up alone from hunger, so i fed him then diaper, the a song maybe then sleep again, and so on and so forth. I began the schedule when he himself wanted to eat every 3 hours, so i think if you stay with the order EASY, you'll get through it!!!
Those are though times but you can do it!!!
