Not that Matthew eats well ever, but him too, he is going through something similar. He used to take 4 yogurts (in his bottles) and some solids and for the last few days, he has not eaten anything, he is really fussy and i do think for him it is the teething. His bottom front have been out for a while but now i can see nothing at the top because he barely lets me into his mouth but the bottom side are starting to stick out. (Don“t know if you can have sides before the top so it is either 2 or 4 teeth). He will not even drink much water from the bottle.
Hope that it is only temporary for Isaac and he feels better soon!
