Ayyy same issue kami dito, ang aming munchkin ayaw din ng rice for a while so we started mixing it with their favorite viand or trying different rice shapes, may time kasi talaga ang kids na ayaw ng plain white rice pero okay lang kung may flavor na kasama! One of my mum friends swears by giving alternatives like bread, pasta, or even sweet potato para sure na may carbs pa rin, then gradually reintroduce rice slowly without pressure kasi sometimes kapag forced, mas lumalaki ang resistance nila.
