My son is 3yrs 7 months old; he has not pooped for 5 days...what should I do? or what medications I can give?

A. Okay right now you can insert an enema into the anus of your child that is going to be your child poop and you should start applying castor oil around the naval of the child before your child goes to sleep also need to advise you to increase the intake of fiber and liquid for your child
