5 mo old nap issues

My daughter has always been an amazing sleeper. She started sleeping through the night at 3 months and has been doing it well ever since.

She’s has a pretty solid sleep routine -

up 6:30-7ish

1-2 hour nap in the morning

1-2 hour nap in the afternoon

Maybe a catnap around dinner time is she’s extra tired but then bedtime starts around 7 and usually asleep by 8-8:30

This has been working so well for about 2 months. Now all of a sudden she is refusing to nap in the afternoon even when she is very obviously tired (long blinks, yawning, rubbing her face). This means bedtime has to move up and so does her waking up. And she’s so cranky in the evenings because she hasn’t napped and is overly tired.

Has anyone else dealt with this?
