First things first: There are 5 major categories of car seats:

Now that those names are familiar to you, let’s go through them individually so that we can help you find the right fit for your child.

Infant Car Seats

The infant seat base is removable and so it stays attached to your vehicle car seat (additional bases are sold separately).
Designed to be used on average from 4lbs to 30 or 35lbs and up to 32” (weight and height limitations vary by make and model of car seat).
Rear-facing ONLY
Bucket style design to properly support developing infants.
Click and Go technology allows you to snap in your infant seat easily into your its base in your vehicle and remove it when needed during errands.
Many brands of strollers will allow you to simply click your car seat, of the same brand, into it, therefore making it a travel system in a flash! Adapters are already included on the stroller.
However, if you use a different brand of stroller than your infant seat, the compatibility needs to be verified. Often times, you can purchase an adapter separately that will allow you to click the two together, creating your own travel system. In this case, make sure the adapters are the SAME brand as the stroller, and compatible with the infant car seat model you are using.

A few safety tips….

Although children can legally forward-face at 1 year AND 20 lbs, it is HIGHLY recommended that they remain rear-facing until at least 2 years of age or even better, until the reach the maximum rear-facing height/weight of their seat. It is also recommended to keep your child in a booster until 63” or 120lbs. The NHTSA advises parents to keep children in their respective seats until they reach the maximum height and weight requirements. Belt position is incredibly important in keeping your child safe in the even of a crash, and car seats allow you to get the best fit for your child.

** When using car seats for multiple children, make sure to check the expiration date and discard of your seat when appropriate. Most seats will last 5-7 years before expiring.
