Loud and high-pitched crying/whining is making me aggressive. Am I abnormal?

I have always hated loud noises, and now that I have kids, it absolutely gets to me when they shout/yell/screech and whine. I have to use earplugs to take the edge off, or else my blood starts boiling and I have to remove myself from them or I feel like hitting them. Especially when it’s something that they want or are frustrated about. My oldest (4.5 years) isn’t doing it too often anymore but my youngest (1.5 years) does it a lot every day. It’s driving me crazy! My dad told me he feels the same aggression with this. Are we abnormal or is this reaction common? via /r/Parenting https://ift.tt/30LcKkC
