A. Hello for ur child to reduce weight you should.be a good role model...it's very important ..encourage 60 minutes, and up to several hours, of physical activity a day. keep to child-sized portions ( hv kids plates at home)eat healthy meals( no chips cookies etc), drinks and snacks. less screen time and more sleep.
