Dropping naps!

When did your LO drop their second nap!? My girl is 15 months old and our schedule is something like this.

Wake 7-8

Nap 10-1030 ish (depends on wake time) sometimes it’s an hour to 2 hrs.

Then nap at 3 to 415/430

Bedtime 7-8.

I’ve tried to push her out and miss the first nap but then we only get an hour and half nap all day from 12-130 if we’re lucky 🥴

How did you drop one? Is something wrong here? Thanks!
