Tummy Tub Video

What babies cry not over the bath belly?? I mean I see videos of newborns on youtube and they are really relaxed in the bath belly and wonder if the mothers of babies screaming just didn't want to post videos ... or all babies do is relaxed and calm during a bath Tummy Tub?
Please tell me, because if I have another baby I might consider this hectic life saver bath first!
Thank U

Well, it depends on baby. many jobs are the best shots they change the tears
