Hi my 1 year old has not pooed for 3 days. Any suggestions to help him poo soon?

Give him apple juice and Set him on the toilet and then have him lean forward while holding on and have his legs more apart then closed and then tell him to push (rub his tummy in clock way motion and when he starts to push..help him by pushing on his tummy for help) then break an breath. ...(repeat).. My 1 year old daughter has bowl problems and that was the only thing that helped her poop and get it out.... Hope that helps if you try it.
