This will vary depending on the manufacturer – as there is no industry standard for teat sizes. When should I change from medium to fast flow teats? However, while this may be recommended, Avent nipple sizes also go to 2 and 3 for a reason. Not every child is the same.

You can see rough similarities in the banding between them – but remember that one brand’s slow flow rate won’t necessarily be identical to another’s. Keep in mind that these time ranges are just referenced points and are helpful for making changes to the nipple size. If you’re unsure if they’re ready, rest assured there’s no exact science to when it’s time to change up the flow rate on your baby’s bottle.

Variable – features an adjustable flow rate that can be change between 1 and 3 by turning the bottle. The number 1 is recommended to use regardless of the babies age if alternating between breast and bottle is the practice.If you’re wondering whether you should change the teat flow, this gives you a rough guide of flow speed by age: Flow rate I noticed with both teats and breast pump parts, such as filters, how the plastic seems to just degrade over time. The Philips Avent Anti-colic bottle reduces fussing. Babies fed with Philips Avent Anti-colic bottles experienced 60% less fussing at night than babies fed with a competitor’s anti-colic bottle. The teat shape allows secure latch, and the ribbed texture helps prevents teat collapse for uninterrupted, comfortable feeding and is made of BPA-free material (silicone). so regulating the flow with these Avent nipple sizes is key in making sure the kiddo is getting the right amount and the right speed.
