The recipient of the gift loves doc mcstuffin but for this one, she was scared of the other pics and dont want to use it so.... need to return.Runs very small and does not fit well on my daughters head. She’s very average size (on the petite side) for almost 4 years old. Her head measurements should work perfectly according to the seller but they do not. Plus it makes her head super sweaty as the vents are not adequate. Do not recommend.I was kind of nervous to buy her a helmet because I thought she would refuse to wear one- but she loved it and wore it even after she got off her bike! It fits her really well and it looks cute too.I ordered this to go with the skates for my 4 year old granddaughter, it arrived in time for Christmas and I love the bright colors and how sturdy it seems. I don't know how it fit yet, but I will update info.I guess my daughter has a big head for a four-year old. It fit a little tight and with her sensitivity issues we don't use it. Maybe for my younger daughter....Good fit for my two year old. However, it doesn't adjust so I think she'll only be able to use it for a few months before she out grows it.I got this for my niece after looking for a girl version of a helmet my nephew (and his parents) love. They tell me it has the same great fit so 2 stars for that, but why in the world does it have fewer vents?! The poor girl loves it for about 10-minutes and then her head starts getting too hot and she wants it off. Why do they think girls need less air vents? Ridiculous.Nice but a little on small side.Very nice, fits my sixteen months old head with no problems, good quality, and very safe!Perfect for. Three year old ! Very pleased with bell helmet and Amazon delivery system. Keep up the good work! We will be back.Thanks. The Ollson's.
