More EMW!

Hi everyone! I’m at a loss for what to do to fix my 18mo EMW. He used to sleep 11.5 overnight but I haven’t seen that in months. I’ve tried longer wake windows and shorter. He goes to daycare M-F. Nap is 11-1. DWT of 6. Bedtime has been 7. I always leave him til DWT. Hes been waking around 5/515 and is quiet, tossing back and forth. Not crying. Wake windows right now are 5/6 nap is capped at 2hrs. He falls asleep quickly and quietly for bed. It’s pitch black. He doesn’t feel cold when I get him out of the crib - but he has been rolling around for an hour…I’ve ordered a higher TOG sleep sack to try that.

Any other suggestions??
