Overview
Description
This cozy Infant Seat Insert creates a flat seat position with extra head and neck support, allowing the Mockingbird Single Stroller and Single-to-Double Stroller (sold separately) to be used from birth (the Bassinet and Car Seat Adapter are additional options for infant compatibility).
The infant insert is made up of three pieces: the headrest, wedge and seat liner (all of which Mockingbird recently updated to a comfortable, breathable mesh fabric). The headrest cradles baby’s head while they’re still developing the neck strength to stay upright. The wedge nests in the base of the seat to create a flatter surface and prevent slouching. The seat liner connects to the seat itself and holds everything in place (Tip: later on, when they no longer need the headrest or wedge, you can still use the seat liner as an extra layer of mess protection for the stroller seat.)
Begin using the Infant Seat Insert with the seat fully reclined. Once they begin to support their head unassisted (typically around 3-4 months), consider removing the wedge while still keeping the seat fully reclined. Keep using the seat liner and headrest until little ones can sit up by themselves (typically around 6-7 months). At this point, they’re likely ready to sit in the seat without the Infant Seat Insert (please consult with your healthcare provider).

Purchased this from the website. Didn’t even last me 9 months it peels horrible, and it looks old after a couple months don’t waste your money on it. Buy something cheaper.

Works for my infant
The infant seat insert converts the regular stroller seat into one that is usable for a small baby. We started putting my newborn in it just a week after he was born, and it worked well. It is secure and safe, and he seems comfortable. This insert saves us from having to buy a separate bassinet since we know our baby will only need it for a few months. Works well for us!

A little big for an infant
I don’t know if it’s because my infant is just 6-7 days old, but I feel like the head protection is not really sufficient the way it would be in other brands. His head wobbles side to side in this chair with the insert attached. I’m going to research to see if I’m doing it wrong or if it’s just like that. But it seems pretty comfy otherwise.

Game changer for our infant!
The infant seat insert made the world of a difference in the ride experience for our little one. It keeps him in an upright position as he is still working on complete neck control and is the perfect addition to his stroller seat.
