At what age did your little ones transition to one nap?

from 10 months

My youngest was between 1.2 and 1.4 years old, I don't remember exactly. My oldest was a bit earlier, around 1 year old.

Lyubanya (oh )

My son, even at 2 years old, didn't nap at daycare.

My son slept once a day at 9 months, but it was a very long nap.
My daughter started sleeping once a day after she turned one.
