Hi everyone, I have a 15 month old, so still pretty young, but he knows how to use a slide. I think I have been able to teach him not to climb up the slide when others are around pretty successfully. However, last night, we were at a play center, and he climbed up the stairs for a slide (good!), and just as he was about to go down, another child came and started climbing up. I tried to tell him to wait, and he did for a brief moment, but the other child continued climbing up, making no efforts to move out of the way. My son slid down on top of the other child. So, I guess technically I don't have a problem with my son doing that last night because the other kid was 3-4 and should have known better. But, in the future, it would be nice to know how to prevent this? Because of the set up, I could not physically stop my son from sliding down on top of the other kid. But when you work so hard to teach your kid the proper way to climb up the steps and not the actual slide in order to go down the slide, it's hard to say, "Hey I know you just climbed up but this other kid is rudely in your way now so you can't slide down." What do other parents do?
