Slightly higher amniotic fluid at 31weeks of pregnancy

Hi Mummies, In my last scan which in my 31st week, my gynae mentioned that the amniotic fluid level is 19 which is slightly higher at that gestational age (range is 8 to 18) The doctor mentioned to cut down on sugar and rice as more amniotic fluid will make baby float more and get into breech position ? Anyone else faced this ? Can you please share your experiences ? First time mom to be here so a bit worried! #firstbaby #advicepls
