Thank you for your replies.
On Tuesday he slept almost 11 hours at night, I think that was by me allowing him to sleep longer in the afternoon and bringing bedtime sooner.
Yesterday, the day was pretty long, he woke at 5:45 and went to bed at 7:40, he had a 40min catnap in the morning, and a 2hour nap in the afternoon.
And he woke this morning at 4:55, I was unable to get him back to sleep.
Today I am going to wake him after 1h40 in the afternoon, to try and get bedtime at a reasonable time so his day isn't as long.
Do I need to start moving the AM catnap back at all to eventually merge it into one long nap, or just stick with it as it is for now?
