Poop problem solve

Hi there have you ever experience your baby having trouble with her bowel movement? Mine was, my daughter has a regular bowel movement when she was about 2 month old, until such time when her bowel movement came every 4-5 days, then sometimes to a week. This really troubled me, then came when she did poop, and man :-( the poop was so hard she cried so much, and it really breaks my heart to see those sad eyes looking at you asking for help,, and i can't do anything to comfort her. I tried calling the hospital and they advice me to use suppository med like(DULCOLAX) to soften her poop,, well it did great,, but still i was not comfortable,, inserting that thing in my babies butt, so i tried asking some people and they advice me to use prune juice,,, so there i am, searching at the department store to find this prune juice,,,we tried it and walla ;-) it did great, sometime my baby poop everyday, sometime every 2 days, or 3 days, 4 the most, but its more comforting than having to insert a suppository :-)
