Introducing a bottle

I've been a little nervous about introducing a bottle because I don't want to confuse Stian and make breastfeeding more difficult. But everything I've read says you really need to do it between two to four weeks for success. If you wait much longer the baby might refuse the bottle altogether. So we finally tried it yesterday. He took it like a champ (although looked a little confused as to why Daddy was feeding him), and hasn't had any problems breastfeeding since then. So hopefully won't have any problems. He had no problems with the bottle again this morning either.
