squirmy changes are a phase, and in our house it was a long one! Move to the floor for her saftey, lay down a portable changing pad for the messy ones. You are t the stage where you find how fast you can change a diaper, haha. During that small distraction from the toy! Good luck.
Standing changes are good! I loved those pampers cruisers they came out when my daughter was 11 months and were a lifesave!
