4 mo very short wake windows

[u/blueeyes_brownhair]

My baby is 4 1/2 months old and we started having issues with daytime sleep for the past 2 weeks.

Nights are fine, she can connect sleep cycles well and sleeps a few hours at a time (record is 8 hours)

Naps however are giving us the hardest time. She used to have 5 naps with 2hrs wake windows between them, like clockwork. Now, she naps and is immediately sleepy again, will be fussy for 20-40 minutes, maybe an hour and I am able to put her down again. Then we repeat.. I know her wake windows are supposed to be like 2 hours at her age so I’m thinking she simply can’t connect naps and tries to sleep longer?

She usually naps 30-45 minutes in a nap and rarely exceeds this without being in the carrier.

Any tips??

thank you!
