mbear, it's a shame thta you had so much difficulty. But with the right information and support nearly every bfing problem can be overcome.

The others have given great advice. Buying formula or bottles ahead of time is setting yourself up for failure. As Barb suggested, an ABA subscription is a far better investment. I was given mine as a gift when DS1 was born and it was by far the most useful gift I have ever received. Before DS was born I'd never have realised how much I would need the ABA. I had a baby who was unable to attach at first, but we managed to exclusively bf anyway.

Good on you for preparing early. I hope this has been helpful for you.
