LO is EBF and I haven't been very good about giving him a bottle just so he would accept them. Now he's 13 weeks and he's only taken a bottle twice - both times over a month ago. When I tried again this week, he refused to have anything to do with it. Any tips on how to get him to take an occasional bottle? So far I've tried two different kinds of bottles (Medela and Dr. Brown's)..
