2nd baby items??

I'm pregnant with my 2nd baby. I have a son that's a year old and I'm expecting a girl this time, I'm not sure of the items I need to get for her of course car seat, clothes & diapers. I'm using my sons swing for her that he no longer uses & his crib, he has his own bed now, so what things do I need to get new for her just curious and asking for other moms opinions😊
