Assuming you would like tips on how to extend a car seat:
There are a few ways that you can extend a car seat. One way is to use an extension strap. These straps can be found at most baby stores or online. Another way is to use a pool noodle or rolled up blanket under the front of the seat. This will help raise the seat up so your child can see out the window better. Finally, you can adjust the straps on the back of the car seat. By loosening or tightening these straps, you can change the height and angle of the seat.
