Constipation

Hello mommies. My lo is 14 months na. And 2 weeks na syang constipated ☹️ I've tried everything, pag inom ni baby ng maraming water, soft foods, laxative (oral - recommend by his pedia) pero using suppository lang talaga sya nakaka pupu. Any advice po? Aside sa drinking water, pag bicycle ng legs niya, warm bath kasi nagawa ko na halos lahat:(
