I have 5 Dr Browns Anti Colic Bottles each 260ml which are less than 3 months old, with size 2 teats. In excellent condition.
No longer needed as baby no longer has Colic. Were very effective in reducing wind/air being swallowed when he was small.
I would recommend these over other brands as the most effective. (also had Tommee Tippee Anti Colic and they weren't as good)
All 5 for sale for £20.
Please message me if interested
