I'd like to keep a supply of breast milk in the freezer so when my husband and I want to go out we can leave our 6-week-old son with the folks and we don't have to worry about hurrying back to feed. We did a "test run" with a bottle of EBM the other day - he chugged it down like nobody's business, but he was gulping air the entire time. His lips just didn't have any suction on the nipple. It was a disaster. He spit up the entire thing - sprayed it everywhere, all over his face, the couch, Daddy.... He didn't seem to mind, but he was hungry less than an hour later.... Any advice on how to fix this?? thanks!
