Such an easy, perfect stroller!
It has everything we need.
Size allow my taller toddler to fall asleep in the seat, which was the bigger struggle in finding a double stroller that wasn’t a side-by-side.
Easy to take apart and store.
Easy to wash!
Totally worth it!

Description
The 3.0 version of Mockingbird’s Single-to-Double Stroller is packed with premium features.
It can be used from birth with the cozy lie-flat bassinet, space-saving infant seat insert or car seat adapters compatible with more than 40 infant car seats (all sold separately).
When baby develops head and neck control, they can graduate to the reversible stroller seat, which offers five recline positions, giving you flexibility as they grow.
The stroller starts as a single and you can expand to a double by adding the 2nd Seat Kit (sold separately). You can also accommodate three kiddos by adding the Riding Board attachment. All Mockingbird attachments can be swapped out in seconds without tools.
The 3.0 features built-in head-to-toe UPF 50+ protection. The FullShade System combines the XL extendable canopy with the Mockingbird-exclusive LegShade to create maximum shade on sunny days, while ventilated mesh panels promote airflow.
A reversible, seasonal seat liner flips from a cushioned everyday side to a breathable mesh side (and is machine-washable for easy cleaning).
More updates include a quick-snap magnetic buckle to help with wiggly toddlers, reflective piping for safer nighttime strolls, extra pockets for both parent and child and a height-adjustable canopy so you can keep strolling even as they get taller.
Little ones enjoy smooth strolls thanks to all-wheel suspension and shock-absorbing tires that never go flat.
Parent-friendly features include an easy one-hand fold, rotating handlebar to accommodate caregivers of different heights, no re-thread harness with one-hand strap adjustments and a generous XL storage basket.

Is the uppababy Aria car seat compatible with the stroller and the adapter? ?
Best Answer: Yes. The UPPAbaby Aria is compatible with the Mockingbird Single Stroller and Single-to-Double Stroller when you use the Mockingbird UPPAbaby Car Seat Adapter, sold separately.
For twins how does it work does it comes with all supplies ?
Best Answer: No. The Mockingbird Single-to-Double Stroller 3.0 does not come with everything needed for twins. It includes the stroller frame and one toddler seat. To use it with twins, you'll need to purchase the 2nd Seat Kit 3.0, which includes the second seat and the required adapters. If you're using it from birth with twins, you'll also need either two car seat adapters, two infant seat inserts, or other approved infant accessories, depending on your preferred setup.

Fantastic stroller

Sturdy stroller
So far we love it! Got it to eventually use the double seater feature but for now my 18 month old is enjoying it very much! Easy to keep clean and holds up well on not paved sidewalks, as it is still new to me and I’m a particularly short person, I haven’t found a comfortable way to open and close it, a little awkward but over all great stroller!

From Doona to Mockingbird
I had a Doona and LOVED it but my baby started to grow out of the Doona around 1 year old. I did a lot of research and wanted a stroller that can grow with us as we plan to have more children in the future. I did not want to buy a bigger single stroller then have to buy a double stroller later on. This stroller will not only serve us now with our 1 year old daughter but can serve us as a double stroller when the time comes. It is perfect for what we were looking for and I could not be happier. The quality is also AMAZING. This is a luxury stroller!!!

Ok double stroller
The stroller works well with one child but hard to push with 2. Especially on the road with the pitch. The handle does not extend but can be pushed up and down. With double attachment it’s a weird shape and takes up a lot of room. Would not repurchase for a double.

Great stroller
I love this stroller and have converted it to a double. Works great, is slightly bulky but all doubles are. I appreciate the large capacity in the underneath storage area and I really love the additional features like the sunshade for my kids legs and the addition back of seat storage! Also enjoy the accessories that can be purchased, they are all really good quality, (the stroller caddy is a must!!).

Amazing stroller
Couldn’t be happier with our purchase. Was worried by an online review that said taller people might hit the brake bar when walking but at 6ft 1” we have never had a problem and absolutely love our Mockingbird stroller. Fantastic purchase and moves so easily.

Not a Great Double Stroller
I got this stroller for my baby shower and loved it for my first baby. We chose Mockingbird because we knew we wanted to have 2 kids close in age, so we loved that it could transform into a double stroller. When we had our second baby, we realized it isn't really a great double stroller, and as she has gotten older, it's only gotten worse. The stroller pulls to the side when both kids are in it, so we're always having to correct it the entire time we're walking (even in a flat street, unless you…
