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

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

Price: $183.90

This car seat is suitable for toddlers, infants, and preschoolers. It is ergonomically and structurally designed to support children from 5 to 100 pounds.

This means it can be converted from a rear-facing seat to forward facing mode after your child has developed to over 40 pounds, and from that to the belt-positioning booster until your child is over 100 pounds.

One reason why I like a 3-in-1 car seat, aside from cost efficiency, is that the child will get used to it and be very comfortable using the seat as they grow up.

But that doesn’t just happen; a number of features combine to make that possible. The number one factor that keeps this car seat good for long is the machine washable seat cover.

It is removable for washing and drying to remove debris and stains, making it very comfy for your kiddo to use and enjoy throughout the journey. Make sure the cover is properly dried before replacing it to avoid irritation and a mess.

If you are not convinced on why you should wash and dry the covers, then the rotating cup holders should convince you because children are very likely to make a mess with the content in their cups.

Nonetheless, a cup holder is a good attachment because it keeps your kiddo hydrated and refreshed on short and log drives.

Pros

● Great design and colors

● Easy to install

● Enhanced safety features

Cons

● Anchor connectors need to be improved

● Hard to pull car seat
