Top three must haves for baby

Ftm mom here: I'm going to a massive baby consignment sale tonight and I would love to hear what you experienced mommies considered to be your top three must have baby items (pls include brand if that's important to know). Let's say besides items like the car seat, stroller and basics like bibs. I'm hoping I can snag some great deals but I am also worried about being completely overwhelmed. Thank you so much!! 💞👶
