My 1 year old isn't eating so well anymore?

my son did the same thing around the time he turned one. He didn't want to eat anything, he acted like the food was poisonous or something lol. I taught him to stick his tongue out and taste, and if he didn't like it he didn't have to eat it. He ended up trying to many new foods and its been working out soo well. Sometimes they just hit a stage that they eat less. For your situation though it may just be her teeth. I use to put my sons binky in the freezer and the nipples to his bottles. It made his teeth feel so much better. The baby teeth gels they make, made my sons teeth feel weird, I'm guessing the numbness it causes and it made him more cranky. To be honest if it were me, I would keep her on her regular bottles until her teeth stop hurting. She might be cranky from adjusting to less bottles. Try the toddler formula. I had my son on that until he was almost 2. Only for sleep times though. Good luck, hope this helps.
