Registry question!

Mary • Mommy to Olivia💖 8.30.08 and Matthew 💙 7.17.19

So I’m lost as to how to register for clothes for this nugget. How much, what kind, do I even register for them at all? I know that at every shower I’ve been to the mom to be has gotten a ton of clothes! I mean surely she didn’t register for all that, right?
