I will be 3 weeks postpartum. I had twin girls. For the babies I packed a going home outfit, an outfit for pictures, onesies, socks and a blanket (it was cold when we were discharged from the hospital) but since it will be summer when you deliver a receiving blanket should be fine. I did pack diapers and wipes but didn't use them because the hospital provided us with those. For me I packed a robe, slippers to walk around in, a going home outfit, travel sized shampoo,conditioner and deodorant. Toothbrush and toothpaste. Also a nursing bra and underwear. I didn't use the underwear I used the mesh ones the hospital provided. They were a lot more comfortable. That's all I can think of that I took.
