What age did you switch out of the infant carrier carseats?

are 7.5 months old and on the bigger side (for twins). was 19+ lbs was almost 18 lbs at their 6 month check-up, but I'm really hoping to get through the winter in the carriers, I can't imagine taking them out of the convertible seat with no coat & putting them in the bigger stroller, although they like that stroller much better. We live near Chicago & it's COLD. I do have the Bundle Me's in the stroller, so I guess they would warm up quickly. I don't carry the infant seats with them in it, except from the house into the garage. 99% of the time the seats go right into the double snap & go. Hmmmm... any thoughts?

Re: What age did you switch out of the infant carrier carseats?

My Twins are almost 13 months old and over 18lbs each. We still have them in their infant carriers. But only because we bought 2 convertible car seats and returned them because we did not like the way they rear faced. Now we are waiting for 2 more 20% off coupons as those suckers are expensive!!! I mean, i would assume that you can get through the Winter. Depending on what the weight limit is on your car seats.
