Shifting Schedules – When to Change from Two Naps to One Nap 
  By Elizabeth Pantley, Author of The No-Cry Nap Solution

 During the early years of life, nap schedules are in a continuous state of change. After a newborn period of all-day napping, babies eventually settle into a regular two-nap-a-day routine. Most children switch from these two daily naps to one nap sometime between the ages of 12 and 24 months. However, that year of difference is a very long span of time. This shows that age alone is not the only factor to consider when changing your baby’s nap routine. 
 
Changing your baby from two daily naps to one nap isn’t about what your child thinks he wants, nor is it about the schedule you’d like to have. It’s about the biological need for two naps versus one. Naps at different times of the day serve different purposes in mind and body development at different ages. For example, morning naps have more dreaming, or REM sleep, which makes them important for young babies who require it for early brain development. You don’t want to rush the process if your child is still benefiting from this important sleep time.
          
There is another consideration when deciding to make a schedule change: The length of time that your child is awake from one sleep period to the next has an effect on his mood and behavior. No matter how well your baby sleeps at night naps are still very important. The older your child is, the longer he can go between sleep breaks without getting cranky. The biology behind this reason dictates that young babies need to divide their day up with two naps, but older babies can handle a full day with only one nap. 
 
Since there is a wide range of what’s normal it’s important to study each child’s behavior to see when he is ready to transition to one nap a day. Use the following lists as a guide.

 Signs That your Child Needs TWO NAPS Daily.

•             Your child is under 12 months old 

•             When you put your child down for a nap he plays, resists, or fusses for a while but always ends up sleeping for an hour or more 

•              When you take your child for car rides during the day he usually falls asleep 

•              If your child misses a nap he is fussy or acts tired until the next nap or bedtime  
 
•              Your child is dealing with a change in his life (such as a new sibling, sickness, or starting daycare) that disrupts his nap schedule 
 
•             Your child misses naps when you’re on the go, but when you are at home he takes two good naps

Signs That Your Child Is Ready to Change to ONE DAILY NAP. 
•              When you put your child down for a nap he plays or fusses before falling asleep, and then takes only a short nap, or never falls asleep at all 
 
•              Your child can go for car rides early in the day and not fall asleep in the car 

•              When your child misses a nap he is cheerful and energetic until the next nap or bedtime 

•              Your child naps well for one of his naps, but totally resists the other nap

 How to Make the Transition When Signs Point to Change

Instead of thinking in terms of dropping a nap it’s better to think in terms of a schedule change. The change from two
naps to one nap is rarely a one-day occurrence. Most often there will be a transition period of several months when your child clearly needs two naps on some days, but one nap on others. You have a number of options during this
complicated transition time:

•              Watch for your child’s sleepy signs, and put your child down for a nap when indications first appear. 
•              Keep two naps, but don’t require that your child sleep at both times, allow quiet resting instead. 
•              Choose a single naptime that is later than the usual morning nap, but not as late as the afternoon nap. Keep your child active (and outside if possible) until about 30 minutes before the time you have chosen. 
•              On days when a nap occurs early in the day, move bedtime earlier by 30 minutes to an hour to minimize the length of time between nap and bedtime. 
 
The Danger of Dropping a Nap Too Soon
It’s my belief that the reputation that toddlers have which is known as the “Terrible Twos,” is very likely caused by inappropriate napping schedules. There are a great number of toddlers who switch from two naps a day to one nap, or – heaven forbid! – drop naps altogether, many months before they are biologically ready. This can result in a devastating effect on their mood and behavior: the dreaded and horrible“Terrible Twos.” 

For those parents whose children suffer the “Trying Threes” or the “Fearsome Fours,” it’s likely your child is misbehaving for the same reason: an inappropriate nap schedule may be the culprit. The good news is that a modification of your
child’s napping routine can make a wonderful and dramatic difference in his day – and yours.
