I have a chariot bike trailer/stroller. It's only safe to take children that are one year or older behind a bike with a trailer and dd just had her birthday. I've been looking forward to taking her for a ride here or there. The only thing is at the bike store I was at they didn't have a helmet small enough to fit her head :( I'm wondering if this is going to be a problem to find one for her. Does anyone happen to have something they suggest for me to look for? The helmets they had only fit at the smallest 44cm heads. I am just itching to take her out, now that the weathers nice, but can't without this important piece of equipment. I don't know how it is where you live, but here it's illegal to ride without a helmet on.
