i find formula easier cos its quicker feeds, so im not stuck to the sofa for 30 mins or even an hour etc, also for feed time at the zoo, sum one else can do it, as my and expressing doesnt happen! but its the knowing if i can feed him when he wants and not when its advised, and he always wants alot more than the hv or guidelines says he can have. but in my opinion, bf u dont know how much they get, and nobody tells baby he has to stop feeding or that he needs more its all on demand. i have a hungry man on my hands.
