He wakes himself from the pm nap, sometimes it's even shorter. I know it's a long day, but I really tried to shorten the afternoon and he simply can't go to sleep before 7...he is so wired up during WD and then he's in the crib by 7, but takes him so long to settle.

I'm not sure about his reflux. He seems not to be bothered by it, he doesn't cry in pain. He doesn't spit up at all...is it reflux if it kinda comes up and then he swallows it back? He does that often...

He doesn't have tummy aches.
He might be hungry now, as he's in the middle of a huge solids refusal, he hardly eats anything. I wasn't worried at first, thinking it's the teeth bothering him, but it's been almost 2 weeks now... So he would eat 5-6 bites only, nothing off the spoon. Of fruit he eats banana and apples, of veggies potatoes, carrots, peas, zucchini, mushrooms- only a few bites at a time. He used to love squash and yogurt, he won't taste either now. He still eats most from bread or toast with butter or cottage cheese and he grew fond of pastry from the bakery. Sometimes I give him chicken or chicken liver with bread. Oh and he has about 5 BFs a day...
When he wakes at night, he is wide awake and stands up immeadiately. If I manage to hear his first fuss, then I can put him down before standing up as his eyes are still closed. When he wakes in the morning or from a nap, he likes to laze around in the crib for about 10 mins, and then he's on the go.
If it's any kind of intolerance, what are the symptoms of it? I don't know anything about intolerances, have to read up if I have time...
