Day sleeping is similar to eating, every child is different. Develop a schedule based on what you see in your baby, and once that schedule naturally forms, try to stay to it. You have to bend your schedule around your child's if you want consistency. In other words, if your baby usually goes to sleep at 7:30 P.M., don't take her to a class that starts at 7:00 P.M. or leave for the mall after 6:00 P.M. Plan your day around baby's sleep schedule, and both of you will be much happier because you'll soon fall into a predictable rhythm.
A lot of mothers get upset that their babies can be so fussy at certain times of the day. I say, "Get used to it and deal with it!" Most of this frustration stems from the fact that Mom has not taken the time to get to know her baby's natural rhythm, and she has tried to make her baby work around her own schedule. Just because you can wake up at 6:00 A.M. to get ready and go to work doesn't mean your baby can adapt to your schedule. It might not be convenient for you to put baby to bed at 7:00 P.M. and wake up with her at 4:00 A.M., but you're only asking for trouble if you plan a big gathering that doesn't get started until after 7:00 P.M., and then get frustrated that your baby is so fussy. Of course she's fussy
