Nap time

My baby will only nap really 2 times a day. She just won’t take to the third nap. She is almost 6 months old.

She gets cranky at the 2 hour mark. So I’m usually trying to put her down right before that.

But then the time between her 2nd nap and bedtime is 3-4 hours (sometimes more depending on how early she woke up that day)

Should I try to stretch out her awake time before and between her two naps or just have an upset baby for 1-2+ hours?

Or any other tips for that third nap? I try not to let her sleep more than 2 hours per nap at most. And usually it’s only like 30min to an 1 1/2 hours at most anyways
