From the beginning try giving the baby something to hold in his hand while changing his diaper... For what ever reason they hate diaper changing and it gets worse as they grow up.. So what's worked for me is I always give bumling something colorful or noisy it could be a toy, a sock, his own tiny shoe... Your soft wallet (with nothing in it!!) somedays A cap.. Something, anything that will distract him from the on going task.. Also it will help in him not turning over... Which is super annoying!!
So a toy while diaper changing... Works like a charm!!
