M.S.
Don't worry too much. Keep offering, but she'll eat when she's ready. Have you tried things like Gerber's cereal puffs that dissolve? She may just be more excited when she's old enough to feed herself little bits of food. For instance, my son, who's almost 10 months has never eaten veggies, only fruits, not even if i "hide" the veggies in fruit. But he's gotten very good at feeding himself, can get things with his thumb and forefinger very meticulously, so I started giving him real peas and he loves them because he can pick them up one at a time and feed himself! Especially if she's gaining weight, it's not a big deal right now, introducing foods around 6 months is more to get them accustomed to eating and digesting foods, but nutritionally they don't "need" it. Except for iron, around 6 months their iron reserves that they've had since birth are starting to run out, but most formulas are fortified with iron, so if she's on soy formula, she's probably already getting the iron she needs!
