M.S.
At 11mos, my son would only eat very cold applesauce for 2mos. Drove me batty and we chalked it up to first year molars. He went back to normal eating until 22mos, where he's on some "typical toddler eating strike" (so I'm told by the peed), where he only drinks water/juice and barely eats (like half a nectarine in 3days). He's lost 4lbs, but the peed says he's in same perentile and doing just fine. Still drives me batty!!! Good luck :)
