Yes, it is too young. It is illegal...even one day before. I saw an article with a mother who got in a wreck with her 11 month old who was forward facing and she was charged with aggravated child neglect. Children under 2 are 5x more likely to be killed when forward facing as opposed to rearfacing. For that reason, my 21 month old is still rearfacing. And feet touching the back of the seat is ABSOLUTELY no problem. You do NOT have to flip them when their feet touch. If that were the case my child would have been forward facing at 8 months. The poster who's pediatrician said that they could suffer leg/hip damage is grossly misinformed. There is not one single piece of evidence that suggests this will happen. BUT there is a lot of evidence that a small child (yes, over 1 year of age) could suffer severe, lethal spinal cord injuries while forward facing. It is called internal decapatation. You should google it. Besides I'd rather have a broken leg than a broken spinal cord....legs can be fixed. I don't say this to scare you, it's just that there is a ton of misinformation out there and some of it is perpetuated by uninformed pediatricians (they are medical doctors, not child passenger safety technicians). My child is off the charts tall and all legs and she just sits frog legged or with her feet propped up on the back of the seat.
The American Academy of Pediatrics recommends rearfacing for as long as the seat will allow.
If you want to learn more, ask your pediatrician about the article that just came out in Pediatrics magazine (it is a magazine for pediatricians) that informs pediatricians to start better educating their patients on the benefits of staying rearfacing as long as possible.
1 year and 20 lbs. is the bare MINIMUM.
