Simple Joys by Carter'sBoy's Pajama Set

How can you label this? I need my kid's name on it for daycare. Thank you.

It's is possible to buy from these combinations one bottom size (2T) and a different top size (3T)?

Why is this order taking so long to get to me? I ordered it on 08/13/2020. In a few more days it will be a month.

PLease let me know if top and bottom are fleece or 100% cotton?
