i BF makon at night and he is formula fed during the day as he was going to child care and when i was at work(i work nights) but now he no longer goes to child care i was thinking about bfing him again so he would still have formula 2 nights a week! but bf the rest of the time!

can i start bfing again (iykwim) how long will it take to get my supply up again? should i start expressing first to get it going or just "chuck him on"?? hehehe

thanks girls
