New Car Seat Debate

Kaitlyn

So I'm expecting our second baby in early April. I recently went into a local baby store just to browse and came across a car seat I really liked. Since my son in only two I know our Chicco Keyfit 30 is still good to use for our daughter. But I have been debating on upgrading to the Nuna Pipa Lite.... does anyone have any thoughts on these two seats and upgrading for a second baby?
