H., yes it seems everyone of my kids did this eventually , they learn they can kick and do things and yell and it changes you, so they try things again, and see how what they do afffects you , i ignored it, and changed him anyway, i was stronger than him and just did it despite the fit, and kicking, he has learned when he does it, you quit, so you can push through, or make sure he has not been hurt , some babies are sesitive, or boys may have some sesitives, and it may hurt when you wipe him, therefore fear may set in, every one of my kids threw a fit when i wanted to dress them i think its just a stage where they learn how this works, ahahha if their fit changes you , they will keep doing it, if you push on and continue doing what you are doing, it will disappear, if it dont dissappear , i would check other factors, that may cause it, which those i do not know, but other readers might know, any way have a great day and enjo life, D. s
