Does anyone’s 18/19 month old still take two naps a day?

My daughter just turned 19 months today. She hasnt been taking her second nap for a few weeks now but it’s been rough because she still gets tired twice a day and cranky. Her nap is anywhere from 10 to 12 depending on when she woke up or if were out of the house or not, and she will nap for two hours.

Then, she usually gets cranky around 3 or 4 and this is when idk what to do.

I basically just act like I’m putting her down for another nap, I give her a cup of milk in her crib with the white noise on and then I leave. She usually drinks the milk and then talks to herself or whines on and off for like a half hour....I mean I guess that’s good? Like maybe she just needs some quiet time and not a full second nap. What is everyone else’s baby doing?😓 I miss that second nap though lol.

edit- im more asking what do I do because she still gets cranky but won’t nap a second time
