i used to look after a boy who never liked his food either though when i met him he was 2yrs old...
- if he likes rusks try toast cut into the same shape or soft things like cheese or fruit, finger food is a good way to introduce him to the concept...
- there is a vitamin that the family i worked for used to put in the food they could get into him i am not sure what its called, has a giraffe on the packet, but it supposedly increases appetite..
- try sweeter foods like pureed fruit (you probably already have though)
-the other thing you could do is put food out on a high chair tray (it will be messy) and just let him play with it.. it will get him used to the texture and chances are some will go in his mouth so the taste as well...
- and if your really desperate you can buy a softer spoon, get it through his lips and gently pull down his jaw with the spoon and quickly pop the food in...
