Thank you for reaching out to us with your question. We know it can be frustrating when your baby isn't sleeping well. Allow me to recap your question before answering it:
I'm confused about how many hours nap time is supposed to be. My daughter is 6 months old and she is not sleeping well at night. I'm kind of desperate. I was looking in the book, but couldn't find how many hours there should be between each process. Could you help me with that? Thanks in advance.
At 6 months, baby should be on a 3-3.5 hour routine (from start of one feeding to start of the next). In that routine naps should be 1.5-2 hours long.
It is important to work at the length of naps so that baby goes through two sleep cycles. Work at good naps during the day, and the nights will follow. If she is not napping well, nights will likely not be good either.
Make sure to stay with the eat/wake/sleep routine and if you need more help, read our article on how Parent Directed Feeding works.
