Our twins are just starting to stand on their own, which is making getting them dressed a bit harder than they used to be. For one thing, my son especially would prefer to stand rather than lie back and let me work. If I let him stand, he takes that as a signal to practice walking. Both of them tend to freak out when I start putting the neck hole of their shirt over their head. Instead of making a fist, they like to splay their fingers as I slide the sleeves on. When there are things to go on the feet (socks, shoes, footed pajamas, etc.), they curl their toes in an awkward manner. You get the picture.
Step one is to find a way to make the changing process work better for now. But looking forward to the future, are there habits we can get into now that will make self-dressing work better when the time comes?
