I just brought a change of clothes for myself to go home in and a take home outfit for my daughter and a diaper bag. The hospital provided me with everything else I needed.
underwear pads nursing bras and if the hospital allows it pajamas
My other two babies seemed to enjoy pooping up their backs when they were first born..sooo u would bring a couple of changed of clothes for the baby. The hospital should provide you with the diapers while you're there, they give you the bulb syringe, a paci, formula if you' aren't breastfeeding etc. you really don't need a lot for the baby. For yourself you need way more in my opinion. They should give you pads, and they give you disposable underwear which I would take advantage of because ruining your own isn't usually preferable if you can help it lol. I bring my own toothbrush, toothpaste, floss, hairbrush, travel size conditioner and shampoo, a towel (hospital towels are horrible), a couple changes of swest pants, tshirts and sports bras. Phone charger and stuff like that.
