Toddler Naps

[DC1stTimeMummy]

I wanted to ask my toddler is 15 months & we aim to have a 2 hour nap between 12-2pm.

As my toddler gets older, would the nap length shorten?

When did your toddler stop their main nap in the day (was it before they started school nursery- age 3)?

I think it was about 2.5 he was definitely before he started preschool nursery. But there was stil about 3 out of a class of about 30 preschool that still had nap for maybe the first 6 months of it.

I think if they start struggling to go to bed or wake up too early like mine did it's a sign that they don't need the nap.
