My son started walking between 1011 months. He also has access to a lot of climbers like this at his daycare. So we thought his 1st birthday was the perfect time to get him this. We are so happy we did!! He loves it! He was able to figure out the steps and slide in a matter of days. We can’t keep him off it. We’ve only had it a couple of weeks and it’s already paid for itself. Eventually it will go outside once the weather is better, but for now we put it in our playroom so he can use it.
