Started using a waist-high changing pad with a strap to keep the little guy from rolling off mid-change lol. It saved my back and cut down on the wrestling matches big time. Honestly just finding that one small hack made the next few thousand changes way more bearable.
Man, that is brutal. I remember those early days with my firstborn, it felt like all I did was wrestle a squirmy potato and swap out diapers. You deserve a parade or at least a really stiff drink, not just a medal. Hang in there, that 10,000 mark is a serious milestone and you made it through the trenches.
