I was thinking of giving it away once he no longer needs it, 8m right now. 2 swings( my room and living room)  bouncer, high chair, walker, play Matt,  car seat(chico). I will definitely keep them, we want another when he is out of diapers, will start trying ☺️. But my question is can we just use the same car seat? We bought it brand new, I know it has an expiration date but I'm not sure what it is
