Around 6 months, your child’s sleep patterns are starting to more closely reflect yours, with a general understanding of day and night. They should now have their longest stretch of sleep at night, for around 11 hours. Around 7 months, if you don’t have one already, it is very important to implement a predictable daytime schedule to help with naps and evening sleep.
Your child should be averaging about 13 hours of sleep total at this age. If they are sleeping nearly 11 hours at night, that means the other 2 hours should be made up in naps. Expect your kiddo to be awake 2-3 hours between naps, with naps lasting 1-3 hours. I advise aiming for 3 naps per day with the 3rd nap in the evening being more of a cat nap.
