Tommee Tippee Easivent Tetina Variflow 0M+ (4×2)

Switching to these variflow teats meant I stopped guessing which flow size my son needed, since he just controls it himself by sucking harder when he's hungrier. The easivent valve seems to cut down on the air he swallows too, because he's far less gassy after feeds now.

My little one figured out the variflow thing fast, he just sucks harder when he's really hungry and the milk comes quicker, then slows down when he's settling. Weirdly handy at 3am when I don't want to sit there swapping teats. No leaks so far either.
