Any dog can jump and land wrong and hurt themselves but the smaller the dog the smaller the bones. The reason we have so many sick dogs is because we have way to many bad breeders and puppy mills who are breeding simply for the money and not doing available health testing/genetic testing and not knowing the generations and lines of there dogs to know if there are genetic illness in the lines to know not to breed that dog. Also just because the parents of your pup where 4 pounds doesn't mean your pup will be 4 pounds if say his grandfather was 12 pounds he could end up bigger it's not just about his mom and dad. Reputable breeders generally wait until a puppy is 12 weeks before letting them go to there new homes so because this puppy is so small and so young you do need to make sure he is eating every couple of hours and know the symptoms of hypoglycemia and have some nutrical on hand in case he experiences hypoglycemia and its also best not to leave him for more then an hour or so encase he has an episode because if no one is there to see it and get sugar in his system he can start having seizures which can turn into death. Also sense he is not with his mom until 12 weeks he could have potty training problems, biting problems and socialization problems so you will need to watch out for those. Otherwise enjoy the puppy stage is doesn't last long.
