PLEASE PLEASE PLEASE measure your child's foot from heel to tip of big toe to ensure the correct fit! I recommend sizing up 1/2 inch for wiggle/growing room
Go by what you are measuring and NOT only by months as EVERY child is different :)
***Please allow up to 1 week for your pair to be shipped! I usually get everybody's out sooner though :)
