Frequently Asked Questions


We have created a chart for your reference based on baby’s age.

Nipple Size Chart

Please note: Every baby is unique and this is just a suggestion based on baby’s age.

All babies have different preferences. However, we know some of our customers both breastfeed and bottle feed with no problem. It is important to use the correct bottle nipple flow size. You should choose the size based on your child’s age.

If baby has been breastfeeding, they are used to warm milk. Before a bottle feeding, warm up the contents by running under warm water or using a bottle warmer. Pour a few drops on your wrist to test the temperature. It should be slightly warmer than room temperature. Never microwave a bottle as it can warm unevenly and be too hot for baby and microwaving breast milk breaks down the proteins and it loses some of its quality. 

If you are nursing, it is recommended that you focus solely on that for the first few weeks of baby’s life to get them accustomed to it and in a routine. Once that is established, you can introduce the bottle at any time. It may be awkward at first as this is a new experience for them.

First, talk to your doctor for recommendations. There are also a lot of great resources and helpful charts online that you can use as a guideline. Check out our blog post for a helpful chart and other tips.

Wawita bottle parts and most brands of breast pump parts are dishwasher safe on the top rack. However, it is highly encouraged to either wash by hand to ensure all bacteria and leftover residue is removed. You may also consider steam clean bags or a bottle steam cleaner to save time.

If your doctor has given the green light to start introducing rice cereal and purees (typically around 4-6 months) then yes. The medium and variable nipple flow rates work well with rice cereal.

Although our bottles are made with borosilicate, shatter resistant glass, they are not indestructible so please still use caution when using our product.

Sometimes your tracking information will be updated if the shipment is out for delivery in your area.

Packages are scanned when they enter and leave a USPS facility. Sometimes a package will be a part of a large batch of shipments on a truck, plane, or otherwise on its way to a sorting facility. It means the package has not been scanned in a while, but is not lost and is on its way to you.
