What adapter do I need for a Bugaboo Frog to pair up with a Peg-Pérego car seat?

Hi, Georgia,

You would need to get a dedicated Frog adapter for a Peg-Perego car seat, which is very hard to find these days. I am attaching a picture of what it looks like, and an eBay link I found such a thing. You can browse eBay or classifieds to find more, perhaps, but there won't be that many of them I guess.

Be aware that this is an old stroller model and some of the newest Peg-Pérego car seats might not work on those older adapters, ideal is to try beforehand.
