New to the world of baby bottles and/or PopYum? Don’t worry- we all were at some point! We know it can be confusing when comparing different baby bottle sizes and nipple sizes, especially bottles like PopYum that separate water from formula- so we are here to help!
For newborns, we recommend starting with a 5 oz PopYum bottle- as they won’t need too much breast milk or formula milk in one setting. If you have a baby older than 3 months, or would like to use the PopYum bottle for longer, we recommend starting with a 9 oz bottle.


With PopYum’s wide design, PopYum can easily be cleaned with a sponge and will not require a bottle brush. All 5 parts of PopYum are top rack dishwasher safe and may be hand washed or machine washed. You can sterilize PopYum bottles using the same methods as regular baby bottles: steam cleaning, boiling water, or sterilizing tablets.
