My 2 year old has always been a greateater but is now refusing to eat her main meal. She just wants yoghurt and fruit! I think she is possibly getting more teeth and has a mouth ulcer. However she will eat crackers and cheese at random time so am wondering is it sore moth and teething or is she just being stubborn? Any help would be appreciated - don't want to get into giving in to her - but if it is her teeth don't want to be cruel!!
