Why We Love It: The Infant Seat Insert is a great option to make the Mockingbird Stroller ready for your infant. It creates a flat seat position with extra head and neck support that allows your newborn to safely enjoy the stroller seat. 

What's Included: The Infant Seat Insert is made up of three pieces: the Seat Liner, the head rest, and the wedge insert. You can also use the Seat Liner alone later on, as an extra machine washable layer of mess protection for the stroller’s toddler seat. 

Age Guidelines: Your little one is unique, and so is the rate at which they develop! Initially, you’ll need to use all three pieces of the Infant Seat Insert with the seat fully reclined. When your child begins to support their head unassisted, typically around 3-4 months, you can consider removing the wedge while still keeping the seat fully reclined. You’ll want to continue to use the Seat Liner and head rest until your kiddo can sit up by themselves, which typically happens around 6-7 months old. When you’re seeing this milestone, your child is likely ready to sit in the seat without the Infant Seat Insert, though we always recommend making these decisions in partnership with your healthcare provider. 

Cleaning: We use durable materials so that dirt, spills, and food can be removed effortlessly by wiping with a damp cloth and mild detergent if needed. For bigger messes, machine wash and tumble dry on low (for the seat liner and head rest pieces only).

Loved the insert!!

We loved the infant insert! It made our nightly walks so much easier since we didn’t have to strap her in her car seat and lug that in and out of the house. I also love that we were able to have her facing us and reclined. 5 stars for sure!

Snug as a bug

My lil guy loves going on walks and we’ve been using the insert since he was 8 weeks old! Highly recommend.

I love the infant insert. It allows me to put my baby in the stroller and she can stretch out and ride comfortably. I prefer this over a car seat adapter so that my baby doesn’t have to stay in the car seat during outings. The infant insert is easy to install and works great.

Love the infant insert!!

I didn’t really care to have a car seat adapter, but knew I’d be ready to go on walks with our little one after she arrived (and did the day we came home). She was measuring small and ended up being born at 5lbs. The infant insert allowed us to safely bring her on a walk the day we came home from the hospital. She’s grown quickly, but we still use it and I know we’ll stay using the seat liner with her forever. Definitely worth the money and so glad I purchased it!! Would recommend it for any newborn as well likely use it for many months.

Great addition to stroller!

I ordered the infant seat insert shortly after having my baby and realizing the stroller would be too big for him. So glad I bought this, great buy!

Love this Insert!

My 5 month old loves this seat and so do I! We used it in a busy airport. We use it for walks and also around the house when I need to be hands free. The three different positions offer so much flexibility. When my baby falls asleep I recline it completely. I love that the stroller folds with the insert attached. Thank you Mockingbird! Well done!

Love stroller, hard to navigate with a heavy toddler in double mode

I love this stroller and how easy it is to set up for double to single and vice versa. Very good quality. My only complaint is because the heaviest kid has to be at the bottom in front, navigating even the slightest bump in the road is so hard as the weight is all up front. I also have a pretty heavy toddler though

Infant seat

After overheating my baby in his car seat this was such a nice thing to have, the insert let’s him lay comfortably abd safely during walks and other outings.
