If you are going to be breastfeeding or bottle feeding, the Boppy is a MUST.
This is a pillow that fits around you for your baby to lay on when he or she is being fed and it is absolutely one of the best things we have. It's more comfortable than a regular bed pillow and your baby can be closer to you when they are eating than if you have them in an infant bouncer or chair. This is especially wonderful for fathers who feed their babies and want to have that closeness. They have different sizes but I have never had a problem with this, traditional, size.
There are also a ton of wonderful covers that you can buy that have different patterns and textures. Or, you can just leave it plain. It all works the same.
There is also a Newborn lounger that you can buy. We don't have this, but it is the only support pillow designed for newborns and preemies. You should NEVER let your child sleep on the Boppy or the Newborn Lounger (due to the suffocation hazard), but you can use it like you would a bouncer for feeding and play.
ETA:
I had on this post regarding the "Newborn Lounger" that it can be used for sleep. I added that to the description since that is how it is described on Amazon. Specifically (from the Amazon website) it says: "Placing baby on his or her back in the lounger also ensures safe positioning, giving baby the opportunity to either look around at his surroundings or close his eyes and nap."
I was contacted by the Director of Marketing with the Boppy Company regarding using this item to sleep. Since the Boppy Company warns against using this item for sleep, I have changed my description. I would like to thank them for correcting me as I don't want incorrect information in my descriptions of items.
