|Well, that's one option...|
...[R]ear-facing children in an infant seat or rear-facing convertible seat are too tall if the top of their head is within one inch of the top of the seat shell. It may also be an inconvenience if they are tall enough to kick the seat back of your car, but this is not unsafe. A child is too tall for a forward-facing harnessed carseat if their shoulders are taller than the highest slots, or if the top of their ears are above the top of the carseat shell.That's pretty rad news for our baby budget: Lamb still has adequate head room. I'm not sure we'll make it to the 30-pound-mark before he is too tall, but I don't think we need to shell out for a new seat just yet.
When we do get there, any recommendations for a forward-facing model?
