Product description

Get the car seat that's built to grow! From your first ride together coming home from the hospital to soccer day car pools, the 3-in-1 Grow and Go Car Seat will give your child a safer and more comfortable ride. Featuring extended use at each stage, this convertible car seat is designed to last through all your firsts with your child.



For newborns to growing toddlers, the Grow and Go can be used in the rear-facing position from 5-40 pounds. It includes two comfortable grow-with-baby pillows to give your new travel companion a snug fit, and they easily remove as your baby outgrows them.



In forward-facing mode, the Grow and Go keeps your child protected in a harness up to 65 pounds. In both rear-facing and forward-facing mode, harness holders keep the harness in an open position. This makes it easier for you to get your child in and out of the car seat. No more fishing for the harness and clips from behind your child – they’re right there when you need them. The QuickFit™ Harness offers additional convenience in both of these stages by letting you adjust the height of both the headrest and harness in one easy step, making it simple to give your growing child the best fit.



When your child is ready to use the vehicle seat belts, remove the harness to use the Grow and Go 3-in-1 Car Seat in belt-positioning booster mode: up to 100 pounds. The headrest still adjusts easily, letting you get the best fit for your child.



As your tiny baby grows into a big kid, messes are bound to happen, but the Grow and Go car seat pad makes cleanup easy. Machine washable and dryer safe, it is also designed to come off the seat easily, with no need to remove the harness. The Grow and Go is designed to provide more comfort to parents too. It takes up less room when placed rear-facing, giving up to 7 inches more leg room for parents in the front seat.

• Side impact protection: The grow and go’s side impact protection helps keep your child safe
• Easy in, easy out: Harness holders keep the harness in an open position so it is easy to get your child in and out of the seat. Rear facing height is 19 to 40 inches. Forward facing height is 29 to 52 inches

Answer:	I also don't like the fabric and so I am looking for another car seat now that is still on the smaller side and can be rear facing

Answer:	Good morning. We apologize for our delayed response. The Guide 65 has been tested and approved for use with an infant as small as 5 lbs.

The harness must still be positioned properly, below the shoulder level for the rear facing infant. When a convertible seat is used for a newborn, each child may fit differently in the seat depending on the child's unique physical development (i.e. longer or shorter torso, etc).

Disney Baby Grow and Go 3-in-1 Convertible Car Seat

Kids grow so fast that it seems to happen overnight. (These jammies fit yesterday!) It’s a 3-in-1 convertible car seat that’s ready to take baby home from the hospital or bring a big kid to soccer practice – and it’s there for you every wonderful moment in between. Let’s face it, life as a mom can be hectic, but with the Grow and Go it’s easy for them to grow and for you to be on the go.

Messes Happen

Reason to Raise Your Cup

Kids always want to take one for the road. That’s why we’ve included two convenient cup holders, just in case they want to take two.

For the best information, we would recommend contacting the stroller manufacturer directly.

Answer:	It would be challenging to add a cover over it. I’d say no.

Answer:	I had it in a small Tortola Camry, fit without a problem
Question:	Does the car seat detach from the base

Question:	Is there a stroller that I can purchase with the car seat? we have a baby trend stroller and car seat but looking for an upgrade like this
Answer:	im not sure. this isnt a seat that you would take in and out of the car though.
Question:	Is this a steel frame
Answer:	It is a hard plastic frame with metal support rods that help it lock into 3 reclining positions.
Question:	Can i change the recline setting anytime or before being installed
Answer:	It really needs to be done before you have it installed because it’s hard to reach the handle when it’s rear facing, and then it’s too tight when strapped in when it’s front facing.
Question:	Can I use this for my 1 year old facing front
Answer:	Yes! My two year old daughter uses it and she is 38” tall and still has room. I believe this is meant to last them until they don’t use a car seat anymore.

Product description

From baby to big kid the Continuum 3-in-1 car seat is there for your family through three different stages from 5-80 pounds. This adaptable car seat can be used in the rear-facing position from 5-40 pounds, and includes a comfy grow-with-baby pillow to give a smaller baby a snug fit. The pillow easily removes when no longer needed. Once in forward-facing mode, the Continuum keeps your child safer in the harness up to 50 pounds. When your child is ready to transition to vehicle seat belts, simply remove the harness to use the Continuum 3-in-1 Car Seat in belt-positioning booster mode all the way up to 80 pounds. In both rear-facing and forward-facing mode, harness holders keep the harness in an open position. This makes it easier for you to get your child in and out of the car seat. No more fishing for the harness and clips from behind your child - they're right there when you need them. The Quick Fit Harness offers additional convenience in both of these stages by letting you adjust the height of both the headrest and harness in one quick and easy step, making it simple to give your growing child the best fit. In booster mode, the headrest still adjusts easily on its own so that you can continue to get the best fit for your child. The Continuum is simple to clean with a machine washable and dryer safe cover that removes easily from the seat. The pad attaches to the seat with snaps so there's no need to remove the harness or disassemble the car seat. Just unsnap and lift the pad away to put it in the machine. The cup holder is also designed to be easy to clean. Just twist it out and put it into the dishwasher to get rid of the goopy buildup that ends up in every kid's cup holder. The Continuum is designed to provide more comfort to you and your other adult passengers too. It takes up less room when placed rear-facing, giving up to 7 inches more leg room for grownups in the front seat.

User questions & answers

Question:	I have a Corolla would I be able to fit 3 of these in my backseat
Answer:	I don't think so. I have 2 of these in a Hyundai Tucson which is a bigger SUV type car and there's not much room between them. If you did manage to make 3 fit, I don't think they would sit safely.

In both rear-facing and forward-facing mode, harness holders keep the harness in an open position. This makes it easier for you to get your child in and out of the car seat. No more fishing for the harness and clips from behind your child - they're right there when you need them.

Quickfit Harness

The QuickFit Harness offers additional convenience in both of these stages by letting you adjust the height of both the headrest and harness in one quick and easy step, making it simple to give your growing child one of the best fit.

3 Position Recline

Machine Washable

The Continuum is simple to clean with a machine washable and dryer safe cover that removes easily from the seat.

Removable Cup Holder

The cup holder is also designed to be easy to clean. Just twist it out and put it into the dishwasher to get rid of the goopy buildup that ends up in every kid's cup holder.

User questions & answers

Question:	Does this car seat come with a base
Answer:	Hello, and thanks for your inquiry! Yes. The onBoard 35 LT infant car seat comes with (1) stay-in-car convenience base.
Question:	Hi, I have a 10 month old grandson , do he still need a rear facing car seat
Answer:	Safest recommendation per current research, is to keep child rear-facing as long as possible, (by law, they must remain rear-facing until 2 years old, or until they are 40 lbs. or 40 inches tall, at least.) That's why they make more and more carseats that have the "extend to fit" type options nowadays.
