My 5 month old sneezes at least 2 or 4 times a day since birth, normal?

As it says really, she has sneezed regularly since birth, I understood to begin with she was sensitive to the environment but is that still the case or might she be allergic to something?

Tbh I never counted my ds sneezes, but I think, unless there's other signs of an allergic reaction I'd just put it down to the fact they can't blow their nose on a tissue when they feel a tickle like we do.
