Mitten cuff onesies are our favorite to use on our little one. Especially when he was just born, it was too hard to trim his nails and having the option to cover his hands without dealing with mittens made it so easy. We also don't use much of the pajamas that covers their legs because the less buttons you have to deal with in the middle of the night, the better.

You'll definitely need more burp cloths. I have about 30 and could use more. Cloth diapers as burp cloths are great since they're so absorbent. We use these the most.

Our baby also loves his Wubbanub and they're nice so baby can practice grabbing things and they don't roll off baby as easily as a regular pacifier would. They have a ton of different animals.

But really overall your registry looks good! You have a great variety of different sized clothes so that's good. The Dr. Brown's bottles are also great, I would just suggest having a large bowl in your sink to soak all the parts without them touching everything else in the sink. Or if you have a divided sink maybe use just one side for baby things. The only extras I would suggest are a small nail kit to keep in your diaper bag, baby blankets to cover baby up in his car seat or to swaddle, and Aquaphor when lotion isn't enough. Hope that helps!
