It would be best to make a list of everything you already have. Then google it. I know Babies r us has a list of what most moms want plus need. I bought so much for my first child ten years ago that this time I know what I want and need. I didn't use half of the stuff I purchased the first time. Hope that helps good luck
My boyfriend & I also bought our daughter her own stuffed animal that she could bring around with her, sort of like her own baby, she can cuddle to! That could be your own personal gift to her<3
Bottle drying rack, bottle cleaning brush, sterilizer for bottles? If breastfeeding maybe a cooler set for the breastmilk? Some of things I got as gifts I thought could be useful :)
Towels, washcloths, detergant, bibs/burp cloths, bottles, formula if planning on not breastfeeding, diaper bag?, blankets, swaddlers, mittens/socks/baby hats... Some things I thought off from top of my head. Hope this helped!
