Milestone not reached yet

Over the last 11 years, we have seen may milestones in our children's lives. Learning to sleep through the night, walk, talk (a little overrated), use the potty, run, get dressed on their own (very underrated), read, write and various other things. One that is very important to me is learning to swing without being pushed. There is nothing that drives me more nuts than the pushing of the swing. This boy can ride a scooter, hit a baseball, punt a football, climb a tree and jump off the countertop. Conner has not mastered swinging yet. He will, but in the meantime the girls and I have tried everything. Maggie has tried swinging next to him to visually teach him. He just sits there and stares and then calls me to push. Abbey, being the smart one, has tried to explain it to him by using scientific terms. This didn't work. Hell, I didn't even understand it, but it sounded very intelligent. I am pretty sure he is just lazy about this. Once they learn to swing, there is a whole world of things that open up for the parent. I have seen other parents at the playground talking to each other while their kids swing on their own. I'm not real sure I want to talk to them, but the option would be nice. You can mow more than 30 feet of the yard at one time. For God's sake, I could actually sit down. It wouldn't happen, but I have a goal.
