Perhaps your kitten just isn’t ready to eat solids yet. Even though his brother might be, this does not necessarily mean that all the kittens will wean on to solid foods at the same time.
The thing that worries me is that you say he is considerably smaller that his brother. Ensure he has a regular feeding time and give him plenty of milk to keep him healthy. If he keeps losing weight, or does not wean soon, the best thing that I can suggest would be to take him to a vet. They will be able to tell you whether or not it is normal that he is not weaned yet. They will also be able to suggest to you various methods of dealing with this problem.
Do you feed the kittens out of the same bowls? If this is the case, it could be that the weaker kitten has not weaned because his brother has been bullying him and stealing all the food. This can sometimes happen with kittens. They are naturally programmed with a survival of the fittest personality. If there are more than two kittens, then the small one might be classed as the runt. To avoid any more instances of this, feed the small cat separately to give it the best chance of eating some food.
It sounds like you may have been forcing your kitten a little to move on to solids at the same time as his brother. Give him a little more time, and perhaps put a little food down next to his milk bowl to see if he if he takes any interest. Then gradually put more food and less milk down until the kitten will eat the solids and drink the water. If your kitten doesn’t seem to improve, though, do take him to your vet, because the reason he’s not eating might be that he’s ill.
