Sir, My two year old son have constipation problem. He does not do potty for continually for three to four days . Thus he face very problem sometimes he yeals for potty but the stool becomes too hard to pass. I sometimes give me gerbisa tabs to pass the stool. But at the same time I think is it safe to give him regularly. I also give him warm fennel seed water. Sometimes he passes the stool easily but frequently he has problem. I give Similac formula milk ,and ragi ,rice,roti  in his food .please advice me what should I do
