hello, My 3 year old son has been suffering from constipation last couple of weeks.His diet consists mainly on lots of vegetables, fruits, water, soy milk, coconut water, quinoa, OJ once a day,salmon 4 times a week and grassfeed beef or lamb. I keep him away from white bread, zero candies, sodas, cookies, sugar. I am giving him probiotic gummies, fiber gummies, one teaspoon of miralax in his morning milk. However, he continues extremely constipated. Last Thursday I applied a liquid glycerine suppository, but since then he hasnt done anything. thank you for your help
