Baby Max is about two-and-a-half years old now, according to his YouTuber mommy. However, we're betting that he still has the same smile and infectious laughter as he did when he was an infant.
In the video below, we see baby Max's reaction to his mom saying "boo," and his laughter is so hysterical that it's bound to make you laugh, too. We can't be sure why the word tickled him so much -- maybe it just sounded extra silly to his tiny baby ears? No matter what the reason, we're loving this little guy's laugh, and his two tiny baby teeth will definitely make your heart melt.
