DS2 is 14wks and ebf. Like DS1 before him he's so far refused a bottle of expressed bm. Actually, he took 60ml from DP once but I think it was by accident and he's never repeated the mistake 
If you had a bottle refuser what kind of bottle worked for you in the end? Or was it less a question of the type of bottle and more just keeping on trying etc
I'd like to be able to introduce the odd bottle a coupe of times a week so I can start going for the odd swim/run in the eves and not leave DP with no way to feed DS2 if he wakes
