J.S.
I wish I could give you amazing advice, but the truth is my 3 month old son stinks at day naps too. He typically sleeps 10-12 hours a night, but during the day I am thanking God if he naps for an hour 3 times a day. I read Healthy Sleep Patterns, Happy Child by Marc Weissbluth and tried to have set nap times and to be consistent, but my son just doesn't nap for long periods of time. All babies are different, but it sounds like lack of sleep is normal, but not always best. Good Luck!
