My 7 w/o baby never seems satisfied after BFing. I BF for 45 min to 1 hr at every session which can be as frequent as every 20 mins. I cannot leave the house and know that my LO is content if I BF. I have to supplement with formula or I have a screaming, hungry baby everywhere I go. She has been like this since day 1. She has plenty of wet diapers and she looks great, I can tell she has gained a lot of weight (dr's appt next week). HELP! I'm about to give up!
