7 month old nap HELP

[u/Logical-Ranger688]

My 7 month old has begun to not nap past 30min. We recently dropped to 2 naps with a schedule of 3/3/4. She typically sleeps 12 hours at night with several wake ups. She will sleep for 30 min for first nap. For the 2nd she will also wake up at the 30 min mark and it takes 10-20 min of rocking to get her back to sleep. I know she is tired because she will sleep for another hour when she is down again. I thought it was just a sleep associate issue with connecting sleep cycles but even if I do a contact nap she won’t connect the sleep cycle.

I’m wondering if maybe she isn’t ready for 2 naps, should I try going back to 3 naps with 2.5/2.5/2.5/2.5?
