Formula+rice

I know rice has no benefits, but I’m assuming it could get baby full. Does anyone give their baby formula with rice in a bottle before bedtime? (For over 4 month babes)

My new boyfriend whom has a 6 month old, feeds his baby formula with rice. lol he blends it together in a blender for it to be smooth. I’m not one to say anything on what he does with his baby but yeah, he said he follows an online mommy site.
