Skipped nap - 5mo

Va

What do I do if my 5 month old tries to skip a nap?? I cannot get her to sleep. She was tired until I laid her down drowsy but awake. Bouncing, rocking, changed diaper, lullaby, naptime routine, doesn’t matter. She’s been awake 3 hours and has to take a catnap at least to get us through until bedtime 😩
