My son is 5 months and does most of his eating at night. It is calm, quiet, and cuddle time. Co-sleeping means i get more sleep (co-sleeping moms report that they sleep better and more than crib or separated mom/baby pairs). It is VERY normal for your baby to still night feed and helps maintain their weight and your supply. Remember, this is but a season of your life and it is over before you know it-for better or worse.
