Has your toddler had a SOFT FOODS ONLY phase?!

Gi

My 1 1/2 yr old used to eat everything. He has a tooth coming in and he just did not wanna eat at all! He's never acted like this before. After a few days, I figured out he wanted to just feed himself with a spoon. He only wants soft foods though, like oatmeal, yogurt, and baby food again. I started making him smoothies too which he loves. He will NOT pick up anything with his hands anymore. I tried putting tiny pieces of hotdog on a fork for him, even pieces of bread (he LOVED those before!) It ends up in his mouth, but he spits it right out and throws it. This is soo unlike him. It's like a switch just flipped. Tell me I'm not alone, and tell me what I can do please.
