So O does not like loud noises. He covers his ears and becomes very up set. When we went to see the Blue Angles we used regular earmuffs and they did not help. We had to leave early. I was sad about leaving because I knew he was excited about seeing the planes but the noise was to much for him. The other day someone suggested that we buy the ear protectors that people use on construction sites. So we gave it a try. Bingo they worked! First O thought they were cool so he wanted to wear them. Second the noise did not bother his ears and I believe he enjoyed the fire works! It was nice that I could enjoy the fireworks also. I have learned over time lots of different tricks to do different things with my boys. This is another one of those great tricks that I will pass on to other moms!
