Has he gotten his canines and molars yet? If not could teething be at play alongside regression/illness?
He only has 6 teeth so it could definitely be that! Now that I'm thinking of it, I remember that DD always woke early when teething.
Interesting point, Marta. I noticed similar with DD also - times where she needs a short nap to settle at BT and then a while later, she's back to needing a big nap.
Despite the short naps and earlier waking, he hasn't seemed overly tired so I'm trying to take it in stride. It makes me wonder if he's OT when he wakes crying but I don't think there's much I can do so I'll just roll with it. He had his needles yesterday also so that may not help
