It’s hard to know why one kitten is so much smaller than the other. It could be normal, it could be that the kitten suffers from parasites or it is possible that the kitten has a congenital abnormality that is causing a failure to thrive. I recommend to have the kittens are checked for worms and coccidia. The veterinarian may also recommend to deworm them to be on the safe side. The best you can do for the small kitten is to have it examined and see if the doctor thinks it is normal or has a health issue. I hope this helps.
