L will be three in a month and dropped the nap at 2.5 yrs.
She gets about 11.5hrs sleep/night but has always been on the lower end of the scale for sleep needs.
Occasionally we'll get a longer night, up to 12.5 hrs after an EBT if she seems particularly tired, but some nights it's just 11hrs (although she still waits for sun on her Gro clock so gets quiet time until then) I think 11.5 hrs is her average.
