My daughter is going to be 3 next month, and my son will be born next month also. I went to target yesterday and looked at swings, and I know how awesome they are and definitely want one. But while looking, I couldn't help but think of my daughter messing with it, pushing it all the time. I know I can obviously try to teach her not to mess with brothers swing, but knowing toddlers I think she might try to "sneak" it and push him and I'm scared. Has anyone had a swing with their other kids and how do the others act with it?
