jonah did not nap well until 18 months…I wish I could help you…I know how aggrevating it is!!! I tried everything- med increase, slinging him to sleep, slinging & rocking him to sleep, you name it. same thing- he’d be up after half an hour, erg. sometimes (rarely) if I rushed in & got him just when he got upafter that half hour, I could get him back to sleep again for another 20 minutes or so…
however, he was good at night, so we had that going for us…
I also tried by giving up on 2 naps thinking the 1 would help…it didn’t but it did in that it made me less crazy to try and get him to sleep 2x in the day…
I wish I had an answer for you
