What time and how long do you have your 2y old nap? My daughter takes like a hour to put to sleep when i do it around 1 and it drives me crazy i put her to sleep at 2 and sjes asleep in 10 minutes but she stayed up till 10 (also fell asleep in 10m)
I had a few struggles like this with my DD. She used to nap around 1pm but struggled to sleep at night so I switched her nap time to 11-11:30 and she went right to bed at night.
