bottle decisions !!

Okay ladies. I'm planning to breast feed & I figure Avent bottles would work better in this case because they're suppose to be easy to transfer while breast feeding because they are made more like a breast nipple. On my registry I put Dr. Brown bottles. I was going to change it & take off the Dr. Brown bottles & replace them with Avent bottles but my husband thinks I should just put both on there in case the baby won't take Avent bottles & we can try the Dr. Brown bottles & already have both at hand. Any suggestions or advice??
