10 wk old kitten not eating

On the 3rd I took a set of kittens in to get their 1st shots.    On the 8th Tut started to lose weight and on the 10th he threw up a round worm.  I dewormed him but he continued to lose weight until the 17th.  He lost more that 100 grams (was 893 and got down to 763).  We took him to the vet but the vet declared him healthy.  He won't eat wet food, tuna or dry food.  He only will eat a spoonful & a half of baby food and he still nurses from the moms.  He cries when he pees except today when he decided to pee on my bed.  He has gotten back up to 789 but still feels "squishy" not solid like he used to.   He runs around and is very playful.  Any thoughts?   We go back to the vets on Tuesday (for 2nd shots & also 2nd round of dewormer).

My favorite recommendation, goat milk, possibly with added egg yolk, if you dont have problems with salomonella in eggs at your place.

Also, some vitamine paste, like Nutrical...

Cant hurt, may help.  At least, as far it is question of nourishent....

Good luck!
