S.; wow sounds like ive been through that before, ahahahahahaha sounds all too familiar, ahahha sorry for laughing, just been there, very hard i understand, however try being just as crazy, like sreaming, and being wild, hahahahh while changing, this distracts them, and you might be able to do it while changing him , however its still alot of work, and they may just learn to act more wild, but a few wild wacked out noises and flailing about may distract him enough to get the job done, however takes talent, ahahahha meanwhile, keep doing what you are doing, who knows it might work however while shopping you might look crazy while changing him, but adult interaction is always beneficial to any child, ahahahha have fun with it, instead of fighting it, enjoy his enthusiasm, however yes very hard to change with those hands always in the way, i understand my 3 sons proved to be such a challeng also, have fun interacting, and acting might be the key word there, ahahhaahha D. s
