My daughter -who is almost 3 years old- never picked up any new foods since she was a baby. She only eats formula milk, yogurt, sliced apples, bananas, and rice cakes. Of course, she does eat candy and sweet cakes of any texture, taste and temperature, but we never give her candy as an alternative for real food.
She never ate anything like breat or meat. She did eat pureed vegetable soup before, but a food advisor told us to stop all non-solid meals as part of a failed program and since then she never picked it up again.
She seems afraid of new foods, even when she's hungry and others eat. We usually sit her at meals with us and offer her what we are all eating, the same thing is done at her kindergarten. She often plays with her food with a fork and even makes a mess with it, she peels hard-boiled eggs, puts salt on it, but she would never put it in her mouth. After she rejects everything and is very hungry we give her a side dish of white cheese with something she does eat.
We went twice for professional advice, once in a known clinic. They told us not to worry and be consistent with meal plans and family dinners. Her two younger sisters eat very well, as do all her peers and friends at her kindergarten.
Psychologically her life is good and stable, she has a clear daily schedulle and is cheerful and jolly at everything. We moved house once but stayed in the same neighbourhood. She looks healthy and well. We never fought with her on the issue. I once tried to put food in her mouth by force, she cried but suprisingly she felt proud of haven eaten a meatball and talked about it.
Of course, I'll follow up any advice with professional counceling and a steady program. Thank you for your concerns.
