Question: Would this helmet fit a 6 and 4 year old?
Document: This is a nice little helmet, but I emphisize the word &#34;little&#34;. The size stated is just too small, and we had to modify it so that it would fit my 2.5 year old grandson. Seller was terrific though
Bought this for our 4 1/2 year old grandson in December, 2012 for his birthday in February. When he got it, it was too small and there is no way to adjust sizes. The return time limit was up and I would have to pay a restocking fee and shipping back to Amazon. It was only $19.99, with a bell for the bike also, so  I am keeping it for his 1 year old brother to grow into.
Does not fit my two year old, he has a big head. I think it would fit most, hoping it fits my next one.
Purchased two, one for each grandson (5 and 4 years old). Helmets fit, look great, and great price. Very happy with the purchase!
I was a little surprised to see that once my 3 year old grand son put the helmet on that he did not want to take it off. The helmet quality seems pretty good and I think would work just fine if it had to. The bell is pretty cheap and when his sister tipped over his scooter the bell flew apart in many parts. We reassembled it and got it to work again, but don't expect it to last long.
My 3 year old has a big head. We know he has a big head so I bought the helmet listed for 5+. It still does not fit right.
i saw other reviews that said similar things. My son just turned 4 - don't think he has an abnormally large head and this helmet, which claims to be a size 5, is way too small. Sits at the top of his head :)  I love the helmet - maybe it would be good for a much smaller child.
Looks great with the Cars bicycle. It fits kind of big for my five-year old son. You can adjust the straps to fit though. The bell is a great addition too. Love this product.
Delivered early! The helmet is perfect for a 22 month old girl who wants to ride her tricycle with mom and dad's help. I have pictures you would love them!
My issue with this was the size. Right on the package it says 5+, however even after installing the smaller padding it's still too small for my three year old (37 month). Returning it. I know my sons head is big, however he fits child sized hats fine but this child sized helmet is too small. The product itself is nice, I just wonder about the size thing.
Answer: yes
