Short answer: do not turn forward facing until you literally have to b/c he has outgrown the seat. Rear facing seats are outgrown when 1 of 2 things happens: 1)the weight limit is reached - 30-35lbs on current convertible seats OR 2)there is less than 1 of seat above the child's head.Most kids easily make it to 2 years still rear facing.ear facing seats are outgrown when 1 of 2 things happens: 1)the weight limit is reached - 30-35lbs on current convertible seats OR 2)there is less than 1 of seat above the child's head.

You should double check for the state you are in but im pretty sure it goes off of your childs age first, and then his height and weight. even if i doesnt, i think15 months is way too young. I have a 3 year old stepson who is HUGE (as a big as a 5 year old) but our state says he has to be 4 to be in a booster. There are carseats that will fit the big kids like that. Look at walmart or targe and try going for a car seat that is like a booster seat with a backing on it.
