Should I limit the length of my baby's naps?

It depends on how well your baby is sleeping at night.

Some babies confuse their days and nights — sleeping more during the day than at night. One way to set your baby straight is to limit daytime naps — especially those in the late afternoon — to no more than three or four hours each. If your baby is napping for too long at the end of the day, it can make it harder for him or her to fall asleep at bedtime.
