Time change


So we live in Texas so we just experienced the fall back time change. My son was too young last year for it to change anything. He now wakes an hour early and since then he fights afternoon naps. No idea if it is due to time change or what. Usually he naps after being up about 3-3.5 hours. His morning nap is usually about 1.5 hrs. Yesterday he didn’t nap at all and today he only napped for 30 min. He turned a year on oct 28th. I don’t feel he’s ready to transition just because he’s missed naps before and is whiny and cranky. How’s the best way to help him transition back?
