Philips Avent Natural Baby Bottle, Newborn 0M+, 2pk, SCF651/23

I’ve had to toss some Avent nipples because of collapsing due to a vacuum being created while baby is drinking vs air being released through the side vent. It’s happened with both size 1 and size 2 nipples, and it happens regardless of whether they’ve only been washed in hot, soapy water or if they’ve also been boiled to sterilize. Not sure why it happens with some and not others, or how to avoid this problem. It’s evident immediately upon placing into service, so it’s not that it’s a problem that develops over time and with wear. It’s quite frustrating when trying to feed a hungry, fussy baby, then having to stop to switch nipples hoping he won’t get too upset before all is settled. Altogether, I’ve probably tossed ~6 nipples. However, when they’re well-working nipples, they’re good. It’s important to mention that it’s also happened with those purchased from a brick and mortar store, not just those received from A, and it’s usually only 1 in a two pack, but not every pack has a bad nipple. It’s truly hit-or-miss.

Overall the best brand for baby tools and accessories

Great product! Slowest flowing nipple on the market. Great for newborns

Todo muy bien.
