Gift Ideas

So, my daughter and I will be meeting her fathers fiancé in a few weeks and I decided a nice gesture would be getting the fiance and her daughter a gift from me and my daughter ive found the perfect gift for her little girl but don't know what I can get her. Do you guys have any ideas that might be helpful please?

SN: I'm getting them gifts as a good gesture and to keep the air clear between us since she'll soon be apart of my daughters life I just want to do something nice. I've gotta big heart so I really wanna find a nice gift. And, I wanna keep a positive relationship between she and I .

Edit: for those wondering I'm 22, so this is a big step for me.
