My little monkey is similar. She'll take wet things off a spoon sometimes though (but other times she refuses the spoon!). But she's very fussy about what she'll pick up in her hands. Fruit is a big no-no, for example.
I swore I would never feed her processed food, and now nearly every day she has chicken nuggets or fishfingers or waffles for tea and it's bugging me.
I'm going to make up some different cakey things at the weekend. Meat and potato, fishcakes, sweet potato and veg, whatever I can find, with a coating of crushed Rice Krispies.
Then next weekend I'll start teaching her to cook so she can cater to her own fads.
