Not eating much

Ally

Seems like little man isnt eating like he normally does. He loved ravioli and rice and that stuff, but he just won't eat now. If I sit the plate in front of him he throws it. So I had to spoon feed him eggs this morning. Then he wouldn't eat his lunch. He ate some Pringles and half a pbj sandwich. He isn't eating much anymore. Now he does have his 4 "fang" teeth coming in so it could be that, but idk. He usually always eats even when he is teething. Mom says its a phase and me and my siblings went through it. But it worries me. She said to make his normal food and if he doesn't eat he doesn't eat. He will eat when he is hungry. But idk. Anyone else dealing with this?
