I'm bfing and it's going great, but really want to introduce a bottle so that DP can help out with occasional night feeds, and so that we can have a night out. LO is having none of it though, and gets really distressed whenever the bottle is attempted. So far we have tried Avent, Tommy Tippee and Breastflow bottles, have tried me being there/not there, expressed breast milk, hipps formula, warm/cool bottles, tried when she is a bit hungry... I'm running out of ideas! Any tips would be most appreciated...
