My DS is 9 months and he still feeds at (roughly) 1130pm and 0530am. We then usually wake at 0730am. He is breastfed but I am of the belief that he will sleep through when he is ready and stop feeding when he is ready. Although, TBH he IS sleeping through by sleeping 5-6 hours in a row You are doing a great job and whether you choose to feed him or not is a decision only you can make. You know him better than anyone.
