Okay, it´s not absolute usual that younger babys got ill, but think about that they come in a new home maybe with new animals and the immunity against things like bacterias and virus (don´t know the right english word for that) is better if the pup is a little bit older.
A puppy's immune system is not immediately available but only with increasing age structure.
