Peltor Ear Protection

Tomorrow is the annual air show Air Force Base for my father works. We've been going there the last 3 years and we plan to return tomorrow.
My concern is that since I'm bringing my daughter eight months, I am concerned about the negative impact it can have on his hearing. There will be many fighter aircraft flight demonstrations (including the Air Force Thunderbirds) and it is extremely strong. We bought the shells Peltor Junior his ear. They fit well and everything, I wonder if this will be sufficient.
Should I buy earplugs for babies and put too much on the ears in the or should I just use the earmuffs alone?

I do not want to hear to be affected by the air show, so I want to make sure I take enough precautions.

Thank you for any help!

I'll try a kind of ear plug. I've never used ear plugs for babies. There is a kind of wax that I use and like is easy to use, you mold on the ear canal opening.

Well, you'll think I'm crazy, but I had to make one of these for my 7 month around July 4. I bought a headband for baby girl (I bought a black because he is a boy!) And was planted on a pair of socks in his ears to ears. They worked great! We were in the middle of a parade of fireworks and he slept all the time! I'm not good at sewing it look ridiculous, but if you have time to do something like that would be great! Good luck, hope this helps.

As long as the atria are thick, they will be fine.
