We think it is very important for young children to get the sleep they need so we want to follow their lead on when they drop their morning nap. Some parenting books follow a different method for knowing when a child is ready to drop their morning nap. Some parents move the morning nap later and later until it is combined with the afternoon nap. While this may be a good option for children while at home this is not always practical depending on your families' schedule. If you have older children at home who need to nap mid-day you might also want your one year old to nap at that time. This is how we handle our toddler classroom nap time.
When you notice your child is skipping their morning nap frequently you might tell them, "I think we are going to try just one nap a day, right after lunch." It is normal to have a week or two of adjustment when you might need to move afternoon nap forward a bit or your child might fall asleep in the morning. But after two weeks or so, your child should settle into the one nap routine .
