Dr. Brown's™ Siliconen Inzetstuk Vervanging voor de Siliconen Babyfles - 150 ml

The thin silicone collapses so smoothly during feeds that my baby barely gulps air anymore, and it’s noticeably reduced her fussiness after bottles. I ordered two extras so I always have a clean one ready, and they rinse out in seconds.

We’ve been through three of these inserts now, and the thin silicone definitely collapses smoothly as my daughter drinks, which has cut down her burping fits a lot. They’re easy to swap out mid-feed too, so I always keep a spare in the diaper bag.

My little one has been noticeably less gassy at night since I swapped in these replacement inserts — the collapse-as-they-feed design really does seem to cut down on swallowed air. They're also a breeze to rinse out after each use, which I appreciate during those 3 a.m. feeds.
