I have a 7 month old baby girl. She is eating solids and has been since she was 5 months old but she's now beening very picky she will only eat her 2 favourite dishes and nothing else it's either chicken or lamb in the baby foods I have tried her on the veges and fruit and the custards but she just won't eat them she clams her mouth shut until I get her one of her favourite dishes any suggestions on what to do??
