I ordered this, rec'd it (12 months) and begin to wonder if it was too small for my grandsons first birthday. I contacted them. they advised to order the 18 months and then return the 12 for refund instead of exchange due to the short time frame before his birthday. I rec'd the 18 months and found the 12 months fit so i had to return the 18. They were very curteous and answered all communication I had with them. Refund rec'd in a timely matter, I would buy here again.
