[on] Presents for new born baby & mom

Hi everyone, my cousin is expecting a baby boy this April! I love the couple and want to put together some thoughtful gifts for both mom and baby. Do you have any favorite gifts you’ve received or would love to get? So far, I’m thinking of a breastfeeding cover, more diapers, or an air purifier. I’d love your suggestions—thanks in advance! Update: I just found out that they already got an air purifier and will be breastfeeding. No baby registry provided.
