28 minute Naps

Ciao Mamas! My baby boy is 15 weeks today. I’m wondering if anyone else has been able to get their baby to nap longer than 28-32 minutes?

I follow wake windows religiously. I’ve started to have him nap in a dark room with the sound machine and weighted sleep sack, but can’t seem to get him past the 32 minutes mark unless I’m holding him.

Would love to hear what has worked for you.
