It’s b/c they’re kids and are selective in what they hear, for the most part. If it’s *really* bad though (like, banging-pots-&-screaming-their-name-&-they-don’t-even-look-up bad), definitely talk to their pediatrician; we were having trouble w/ our kid (29 mo) even responding to us, & it turned out he was partially deaf! And it’s common for seemingly-unhearing to be a symptom for other medical things, too (not necessarily just deafness).
