Is there a snugride carseat for infants that are over 22 pounds. My son is 4 months old and 18 pounds.?
I am certain that he will reach the 22 pound limit before he is a year old and ready for a foward facing seat. It would be nice to use the same carseat base we have for the Snugride because we own two, one for each car. Any suggestions?

Its about time to move him to a "convertible" car seat. These are the kind that stay in the car all the time, but can be both backwards and forwards facing. Always remember, no forward facing until 1 year AND 20 lbs.
Convertable car seats, which at the kind you need don’t use bases. You will need a seat for each car or to move the whole seat each time.
wow big boy
You should invest in a Britax Marathon, they have the highest safety rating and last for a long while, but you have to make sure he hits the 22lbs. before you face him forward, the Britax are convertible so for now he could be rear facing, and then when it’s time to turn him around you are good to go. Happy Shopping.
You’ll have to purchase a new car seat that is designed for children who reach in excess of the 20 lbs maximum before he is a year old. I had to do it with my first child, and though they’re often more expensive…. well, let’s face it, you can’t put a price on your child’s safety.
Here’s a few links to some of the several car seats that are out there.

There is a SnugRide called the Safe Step 1. It is only for rear facing infants up to 30lbs. It will NOT work with your current SnugRide or SnugRide 2 bases, though. I would suggest a convertible carseat. Remember, no forward facing until 1 year AND 30lbs for the SAFEST ride for your infant!
Unfortunately, when he gets bigger you’re gonna have to move him out of the bucket and into a bigger carseat. Are his feet going over the end of the carrier? If yes, he’s too big to be in there.
Wal-Mart has some really good and affordable car seats. Don’t put your growing boy at risk because you are too cheap to upgrade to one his size.
