Hi Ashwini, Congrats on new arrival. My son also cried when he passes urine. Diaper irritates the baby esp baby boy. Now My son cries if i put him on diaper while going out. My paed advised not to use diaper much as it leads to urinary infections. Whenever I go and tell this kind problem, first he insist me that not to use diaper. As others suggested use cloth diaper. After he passes urine clean the area with soft cloth dipped in warm water and put powder. I did this for my son.
