Yes, the weight limits on all our convertible car seats starts at 5lbs. The newborn must also meet a length requirement where the top of their shoulders reaches the lowest harness slot on the seat.

Yes, they are required while your child is sitting in forward-facing. They are optional but recommended while sitting in rear-facing. The center buckle pad is required at all times.
