Amanda calls this "toddler diaper ju-jitsu:"
Our almost-2 year old occasionally mounts a violent protest when we try to change her. Sometimes, offering her a "standing change" works (and, if you haven’t tried it before, it’s surprisingly easy as long as your kid is standing, not dancing or walking). Otherwise, we’ve had last-ditch success by offering her a "pull-up" — a regular diaper with one tape already closed. She pulls it on over one leg, and I fasten the tape on the other side. Big smiles all around.
