Hi! My LO is 7 months old. He recently started short napping in the AM (after 30-45 min, wake-up - but I'd often be able to get him back to sleep for another 45-60 min -- but not always!). I figured out he didn't have enough A time. This same thing happened at 12 weeks and for the exact same reason. I really really watch his sleep cues, but honestly as he gets older, they are less distinct! Sometimes there's lots of yawning in the AM, which is confusing. Also, now that he's older he fusses from teething, getting bored, etc., so that isn't always reliable as a sleep cue! Anyway, I accidentally kept him up longer one morning, and lo and behold his nap went back to it's regular length! (1.5 hr).
Here's our current routine:
Awake 7 am
E 7:30 (bottle)
Solids 8:30
S 10-11:30
E 12:00
Solids 13:00
S 14:30-16:00
E 16:15 (try to get this bottle in early since we have another before bed)
Bath 18:15
Bedtime routine: books, bottle, song, bed
19:00 bed
10:30 dream feed (hope to be dropping this SOON!)
This routine is working really well for us now. If the AM & PM nap are less than 3 hours in total, then we sometimes add a cat nap in there to help him make it to 7-7:30 pm. But for the last week or so, the cat nap has been history. At 6 months, he still definitely needed that cat nap as he was only doing about 2.5 hours of awake time.
YOu might play around with that first awake time a little by making it longer in 10-15 minute increments, and see if that helps. When I first did this, he still had a stirring/minor wake-up at the 30-45 minute mark, but his eyes remained closed and he clearly wanted to go back to sleep. After a couple of days, he got used to the new routine and is now sleeping thru without a peep like he used to.
