I've read two different "expert" opinions on bedtime for babies. One is that it should be at a consistent time every night regardless of how they napped that day, the other is to be flexible and allow a child to go to bed earlier on days when he seems extra tired/when he's napped poorly. I have had trouble with DS (now 14 months) having erratic napping patterns and I've never stuck to a rigid bedtime. (That said, his bedtime would vary by no more than 45 minutes). I've wondered whether sticking to a very strict bedtime hour (never varies by more than 10-15minutes), would help regulate his sleeping patterns during the day? Any thoughts?
P.S. Keeping him up on days when he hasn't napped well is brutal and usually means he sleeps worse that night -- which is why I've always tended to just put him to bed whenever he's tired.
