Gifts for someone with a Mockingbird Single-to-Double Stroller (3.0)
- Seat Stroller seat with canopy, second seat optional
- Adapters One Car Seat Adapter covers more than 50 infant car seats
- Accessory family Mockingbird lists parts for the Single-to-Double Stroller
The model numbers are Mockingbird's own item codes for the stroller, since it prints no code on the frame beyond the generation. Mockingbird marks every accessory page with the strollers it fits, and the Travel Stroller is marked as not compatible on the same pages. Mockingbird identifies this stroller by generation rather than by a code on the frame.

Mockingbird
2nd Seat Kit 3.0
$175 at Mockingbird
Made for this model
What it adds: A second seat and the adapters to hang it, which is the whole reason to own a convertible frame rather than a single.
Why it fits: Mockingbird names this kit 3.0 and lists it as compatible only with the Single-to-Double Stroller 3.0, ruling out both the single and the travel frames.

Mosquito Net
$20 at Mockingbird
Listed by the maker as compatible
What it adds: A net sized to the full-size seat, for evening walks and holidays where a canopy alone leaves the feet exposed.
Why it fits: Mockingbird marks this net compatible with the Single-to-Double Stroller 3.0 family and not compatible with its Travel Stroller, which is a different seat size.

Mockingbird
Cup Holder
$25 at Mockingbird
Listed by the maker as compatible
What it adds: A holder that mounts on either side of the frame and flexes around different cup sizes, so it takes a flask as well as a bottle.
Why it fits: Mockingbird lists the cup holder as compatible with the Single-to-Double Stroller 3.0 and rules out its Travel Stroller, which has a thinner frame tube.
