Someone suggested tshirts instead of the cones of shame (which are painful after they bump into you time after time after time). They work pretty well. You have to gather up their 'skirts' with a rubber band when they go outside. Abby's shirt says 'Please Excuse My Dear Aunt Sally' - extra points to the first one to know this phrase.
Note of concern - at 8 months of age, Tar now weighs 101 lbs.
