new jammies

Loving these new jammies from costco. light weight enough so that she doesn't roast in bed, but warm enough so that her Tootsie stay warm with the air conditioning on. tonight marcella took a shower instead of a bath. i call it the "rain" and usually she says no and just stands in the tub while i soap her down...but tonight she said "yeah" with her crooked little smile. she's never really liked sitting in the bathtub. the people that owned our house before us put those no-skid things on the bottom of the tub and i think she doesn't like how they feel on her bum. any suggestions on how to get them off without leaving the sticky parts behind and have to tub clean??????? i've tried but it leaves the edges of the shape and well, it looks gross!
