@tavott Definitely worth a shot its so much trial and error, it doesn't help that all kids are so different though right. Hopefully something works for you!
@carleo Another vote for more sleep, my 3 year Olds will sleep 13 hours a night if we don't have to get up earlier for daycare, and are still having the occasional nap too. At 2 they were having a 2-3 hour nap and sleeping 10-11 hours at night.
