Pls help !!

So I just recently had my baby on September 3rd and the doctors wanted me to feed him every 2-3 hours , and sometimes wake him if he needs to eat. Well today he has been sleep all day ! He ate about maybe 8 times today so far since 12 am and the last time he ate was around 4:55pm . Since then he has been sleep and when I wake him to eat he won’t or when he is awake he still won’t eat and now I’m leaking from the breasts and I’m just so worried. Is it normal for him to go this long without eating? Should I be concerned or will he just eat when he’s ready?
