I don't really know a ton about this stage but my son is suddenly getting more and more difficult every day. He gets mad if I say his name or try to feed him, anything ticks him off! I cant even play with him because he wants to play alone. He also will act hungry and I will make him food but he won't eat it. He runs the other way and throws a fit. I'm worried because he's only getting fluids now and not much proper nutrition. This has been for about 5 days now. Hes not sick that i know of, no symptoms that i can point out. But the attitude has been progressing over the last couple weeks. Is this the dreaded terrible twos already? He's 18 months.
