Does the manual say? My chicco infant seat says no insert after 11 lbs so I'd think the convertible would have specifications too

Look it up, but it is normal for the legs to be hitting the seat. As long as they meet the height requirements they are ok.

I used it for a few days...so around 7 months.

@Mrsbells: Yep. It's completely normal and safe. Here's a little bit from The Car Seat Lady. (It's about safety, which I know we're not talking about, but it does address the leg length issue.)

"What about my baby's legs?
Many parents and even some pediatricians mistakenly think that a child should turn forward-facing when her legs touch the back of the vehicle seat, thinking that this leg position is uncomfortable and/or unsafe. This is untrue. In our experience installing 15,000 car seats, we've seen hundreds of children over the age of 1 riding rear-facing. Many of them are very verbal 2 and 3 year-olds and none have complained of their legs hurting. While your 2-year-old may look cramped riding rear-facing – as they sit with their legs crossed or in the “frog-legged” position – rest assured that they are both safe and comfortable.

Have you ever watched a 5 year old sleep in the car with their chin on their chest? Kids are much more flexible than adults and can sit and sleep comfortably in positions that would make an adult very uncomfortable.
Simply put, there are ZERO documented cases of rear-facing children breaking their legs, hips, feet, etc., due to their feet touching the back of the vehicle seat. However, since it looks plausible, this rumor persists. Studies show that forward-facing kids are actually more likely to have leg injuries.

Unfortunately there are too many documented cases of head and spinal cord injuries due to children riding forward-facing too soon. Modern medicine can easily fix a broken leg, but not a broken neck."
