Another all-around favorite, the ABDL "NUK" ADULT baby bottle is a great choice for those looking for a venting system and a design with a wide base and shorter nipple, and best of all — ease of cleaning.
It doesn’t have a bunch of tiny pieces to deal with. (In our book, parenting is complicated enough. If there’s something you can simplify, it’s a win.)

Parents love the shape and ease of use and report that this bottle has a high acceptance rate by ADULT  babies. It comes in several sizes and nipple flow rates.
