My toddler is usually a pretty okay eater. He’s open to trying new foods but the last few days he has been refusing to eat food, even the foods that he normally likes. I’ve noticed he will chew the food but wont swallow and will spit it out and sometimes he will gag like it’s making him feel sick. I’m not sure why he’s doing that. I am a little concerned. Should I take him to see the public health nurse? Is there anything I could try to help him?
