We got some Baby Skates for my son.
He's 18 months and has been on the ice twice. The first time he was 15 months and had just learned to walk - he didn't have the double blades and was in the smallest rentals available. That pair was still too large for him. I pretty much supported him the entire time, but he had fun. The second time was this past weekend with the double blades. It took him a minute to get used to walking in them. After about 30 minutes on the ice, he was able to stand by himself (with me close by) as well as march! I was floored.
If anything, this is great since it allows my whole family to skate! I coach full time and my daughter skates recreationally. My wife started to skate after the birth of our son, but we had to take turns watching him.
http://www.coachseye.com/MePLI'm a much bigger fan of the double blades than the walkers (as seen in the video) that allow skaters that shouldn't be able to skate fast zoom right by you uncontrollably. I've had one kid run into the back of my knees while I was working with one of my adults on crossovers.
