We will keep her RF until she is 40 lbs, according to her car seat, but she'll be in a car seat/booster until she is 80 lbs or more.
how old is your toddler & are they FF or RF in their car seat? - Page 7
My daughter is almost 15 months old and definitely still rear facing. She'll be rear facing until she literally can't safely do it any longer (too tall or too heavy, whichever comes first). She won't be forward facing for a long time to come, either, because her seat is a TALL one and RF up to 45lbs, lol.
My older son was rearfacing 90% of the time until he was 3.5 yrs old or so (90%, b/c I allowed him to ride forward facing a bit younger w/my mil and friend for ease for them and towards the end of my pregnancy w/my second b/c I couldn't help him into his seat). My second son has been riding ff'ing since 27 mos or so, but only b/c he's really long torsoed and tall and we couldn't afford a new carseat to keep him rearfacing. We already have several convertible carseats and he's maxed out all of them rearfacing.
This was our case too, our DD would also get mad about her feet/legs being crammed up in RF position. So after her 1st b day we switched
DS2 is 2 years, 3 months and FF, has been for awhile...we were without my van from October until just a couple days ago. He didn't fit rear facing in the car I used or in DH's little car to go anywhere. So that would've been about a month before age 2. He'd be FF now in the seat I have anyway, it goes RF to 30 pounds and I know he's got to be at least that now, he hasn't been weighed in a few months and last time he was 28 lbs.
DD I know I went to about 18 months and then FF her because of height. She's very tall, everyone thinks she is at least a year older than she actually is.
DS1 I don't remember what I did to be honest...I know I went a little past a year for sure, and I know he was only about 18 pounds at the 12 month appt.
DS3 will stay RF probably until he asks.
