My 12 week old is ebf and I am struggling to get her to take a bottle of expressed milk . I did try her from a young age a couple of times but gave up when she was diagnosed with refkux and a cows milk protein intollerence. I also have a toddler so I struggle to fit in in during the morning. so far I have tried the medela and dr brown bottles but haven't been successful. Have I left it to late ? I am starting to panic .
