This little child sounds interesting. Are you close enough to your cousin's family to know how this situation came about? Usually, there are three broad possible explanations for a child's strange feeding patterns: (1) ignorant and neglectful parents who don't feed the right foods, (2) the child has hypersensitive taste buds and things do actually taste wrong in her mouth, and (3) some children have a more "contrary" personality than others and they do these things in defiance of some of their parents' wishes, just for the joy of feeling powerful.
If you think about what's going on to cause her behavior, you might find a useful strategy. I have a 6-year old granddaughter who wants only blueberries and grilled-cheese sandwiches. I think she is a little of #2 (hypersensitive taste buds) and a lot of #3 (defiant child). I've done things like let her dip a food in a dish of water to "wash off some of the taste." Yes, it's a ploy, but it works sometimes, along with a whole bunch of other tricks. My underlying strategy, though, is to accept and validate her pickiness so as not to increase her defiance, and give her lots of power when it comes to making other choices.
Let us know how it's going.
Child's mother has a lot of psychological issues. I am afraid that child has also inherited it from her mother. Lately, she has been diagnosed for having pituitary gland problems and 90% of it has been cut off.
But still she (the mother) has a lot of Nerves problems and she is close to Nervous break down. Soon she has to go to the Nerves Clinic for 8 weeks where she will have no connection with the outer world including the family.
Actually I feel she (the mother) needs more help than the daughter.
The child has extra sensitive taste buds (the biggest problem).
She also has Problem no 1 too (mother cannot cook while all kind of work brings a lot of load to her nerves and she starts weeping or start abusing people around her). But father does his best to cook, but he cannot control all the things while family is little broken due to the mother.
She may also has the problem no 3 too (at least to some extent). Her behaviour is childish as compared to her age.
She is changing though with her age. She is now drinking a glass of raw milk every day (not grass fed milk). She has started eating a little ground meat. She eats only fish finger. But still no vegetables or salads.
Is there any good supplement for children in America? (I can order through iherb.com or on amazon for world wide dilivery).
Also, the next big question will be how to help her mother too.
