Last year, taking earplugs saved us because everything was sooo loud and without them DS would have been terrified. We bought the kid's silicone kind that you roll up in a ball and place over the ear canal. Unfortunately, they were hard to keep on and kept falling off. What kind of earplugs are the best for little ones? Anyone have any good experiences with a certain type? DS is almost 4. Thanks so much- we're one week out and trying to remember all the little details right now.
