@Lisa this is a good plan, thank you! How tall is your son?
I haven't measured him in awhile but he's tall for his age. At least the height of your daughter
@Lisa I took her to the bike shop today and am gonna go with 16inch, her feet don't touch the floor but they do reach the pedals okay and there's stabilisers so it should be fine!
We just took our son into a shop on Monday as we want to get him a bike for his birthday in April. We're getting 16inch as he tried his cousin's 14inch and he needed it on the highest setting so it wouldn't last long. He was on tiptoe with the 16 inch
