People that dropped to 1 nap at 11 months.

How did you know they were ready? My son is 1 in 10 days so he’s closer to 12 months but naps have been a struggle. He’s fighting both naps and even crying a little at bedtime and taking a bit longer to fall asleep than usual. He’s already at 3.5/3.5/4 and bedtime is being pushed to 8. I’m also already capping naps to 2 hours even tho he pretty much does that himself. His first nap he woke up at 55 mins which used to be 1.5 hours. And even having a shorter first nap he’s still fighting the 2nd nap and needing assistance. This has been going on for a week now. Also I should mention his night sleep is still the same if anything it’s actually longer than usual probably from fighting naps all day and not napping that much lol. I’m scared to drop to 1 nap because I’m just not sure if he’s ready yet.
