Hi,
Those early days of breastfeeding can feel like you are living in a pressure cooker - you feel like you *have* to make a decision one way or another - NOW! And unfortunately, it can mean you make a decision you later regret. There is no reason why you can't go back to breastfeeding, at least partially, but probably wholly. You do need the right information and support though - you've been through a lot. I would suggest you get in touch with a Lactation Consultant. If you let me know (by PM) where you live, I can probably recommend one.
The sooner you go back to breastfeeding, the easier it will be - so try to put her back for at least some feeds straight away. Your dh - was he always against breastfeeding? Or is it a result of seeing what you went through. Might help to ask him why he is feeling the way he is.
Warm Regards
Barb
