How long does a baby have to face backwards?

In a carseat? Does it go by age or by weight?

both... however the longer you keep them facing backwards the better!

Legally it's 20lbs. and one year old. But now they're saying to keep them backwards to at least one year and up to whatever the weight limit is on your carseat.

Both. They have to be 1 year AND 20lbs

Both!

The new recommendation is 2 years old AND 30 lbs

It's one year AND 20 lbs but I plan on keeping Nathan rear facing until he's 2 and 30

Quoting Kelly56 *NOBAMA*:“ Both! The new recommendation is 2 years old AND 30 lbs”

Yep same up here in Canada. Lotsof parents are following this rule now. its much safer  

well legally has already been said, but we are rear facing to the capacity of our seat which is 35 lbs and 36 inches i think.

Ditto. I don't wanna chances with Kairie's pretty little face in an accident  

ahhh Koen was 17 lbs at 3.5 months..
he's going to be 20 lbs in like a week lol

My hubby is a firefighter/medic who installs carseats professionally. You want to keep the baby facing backwards as long as you can (factoring in their height/leg room). This is safest in an accident and does no harm as long as the baby can remain backwards comfortably. Sucks b/c you can't see them in the mirror though, eh?

Its kinda tricky cause what if your baby is already past 20 lbs but is only 8months old?

yes mine is 20 lbs and his feet are just about smooshed against the back seat :T there would b no way a 2 year old would fit sitting that way! there feet hang off the carseat/plus they need a bigger one ????

Yes I aggree, the longerthe better. And they do have those mirrors for baby, so you can see them in your rear view .

One year and 20 lbs. If the baby doesn't meet either requirement then they cannot face forwards.

There are convertible car seats that are both forward and backward facing if the baby becomes to big for the infant seat before their 1st birthday.
