Hi, My son 18 months,has been suffering from constipation from past 1week.while pooping, initially it's like very hard stools,after that it's normal.i didn't change formula of milk as well.giving lots of water ,day to day increased,prune juice,fruits ... everything tried. He is not crying while pooping,hope no Fisher near Anal. He is giving pressure,to come out the stool,so I heard giving chawanprash is helpful, is this true? If so kindly suggest brand name n quantity to give. kindly suggest me Any alternative remedies/ways.
