It is general recommended by breastfeeding experts to wait at least three weeks for breastfeeding to be somewhat established before introducing a bottle in order to reduce the risk of nipple confusion. While some babies given a bottle in the first three weeks will not experience nipple confusion. there is really no way to know ahead of time if a particular baby will be one of the lucky ones that won't.
Regarding fathers and bonding, it is not necessary for the father to be involved in feeding the baby in the early weeks in order to bond. My DH can attest that he bonded just fine with his newborn son through other activities other then bottle feeding in the early weeks. I have also heard from others fathers who bonded with their newborns just fine without giving bottle right away (or ever in some cases).
Some of the activities dad can do to bond with his baby are:
* Hold the baby, cuddle with the baby, rock the baby, etc.
* Give the baby a bath.
* Take the baby for a walk in a sling or other carrier.
* Interact with the baby through singing, talking to it, etc.
