As a general rule of thumb if baby wakes after the 30 minute mark, she is overtired. She may need shorter wake times, or less stimulation during the wake times. If she is waking after the 30 minute mark and is upset, something is most likely bothering her (hungry, uncomfortable, cold, etc). If she is waking after the 30 minute mark but wakes happy, she may be undertired- meaning she needs longer wake times throughout the day. Sometimes a schedule change needs to be made. See questions 3, 4, 5, 6, and 11 above for more help on this. And see the wake time chart in this post for ideal wake times by age.Full postu002du002du003e Waking early from naps- what to do  This post is broken down by age. Other times, you are not quite ready for a schedule change, and baby isn't ready for extended wake times. So you have 3 options: If your baby wakes early, you can simply feed and start a new eat, wake, sleep cycle on the adjusted schedule.Your bedtime in this scenario is often earlier than normal. You can do an EWSW (eat, wake, sleep, wake) cycle.Your baby wakes early, and instead of feeding immediately, you give her restful awake time, and then feed at the normal, scheduled time. Make sure your baby is not waking out of hunger if you choose this option.Read about the eat wake sleep cycle here. When baby is old enough (4 months +), you can simply leave her in her crib until nap time is over.I often have a rule that I leave our daughter in her crib for a full hour from the start of a nap.
