Moms note that flow is printed on the teat and should be matched to the baby's age; you can carefully prick it for more flow with a clean fresh needle, and teats can be swapped within the same Avent bottle and bought separately online or in stores.
⚠️ Caution:Pricking a teat too much can make flow too fast and increase choking/gulping risk - use a clean needle and check the flow before feeding.
Parents of a newborn struggling with a slow-flowing bottle worry the baby isn't getting enough and wonder if it's safe to alter the teat. The community reassures that flow is age-graded and printed right on the teat, that a careful prick with a clean needle is fine, and that simply moving up a teat size - easily swapped within the same Avent bottle - usually solves it.
Here's what moms in our community shared based on their own experience.
The flow is mentioned on the bottle - buy according to your baby's age. Yes, you can prick it; just use a clean, fresh needle.
Yes, you can change the teat/nipple size in the same Philips Avent bottle - the teats are sold separately.
Avent teats are available online (Amazon, FirstCry) and in most baby stores.
Change nipples every 3-4 months even if the size doesn't change. As babies outgrow a size their suckling energy increases - seeming disinterested or chewing is a sign to move up a size.
