Most new moms will need between 2 and 6 baby bottles. Breastfeeding moms will need around 2 to 3, while formula-feeding moms should have 3 to 5.
Stay-at-home moms will need a smaller amount than working moms. A working mom should have one bottle for roughly every two hours of daycare.
Some moms will prefer to have spare bottles on hand to avoid excess cleaning. Disposable inserts and nipples can also be used to bulk out the number of bottles on hand without having to buy extra.
These single-use items are safe to use on the go, and should be thrown in the trash at the end of feeding time.
