I took for myself a nursing nightgown, underwear, socks and flip flops, a robe, a change of clothes for going home, soap, deodorant, toothpaste and toothbrush, hair tools, snacks and money to order out, a pillow, a blanket, and my charger.
For baby 3-4 onesies and sleepers, socks,(hospital provided onesies for use while there but because they belong to hospital and possible been used I brought my own), a outfit for pictures, blankets and coat/ jacket depending on weather.
I took home as many pads as possible, because the stores don't make them that big and my co-pay was 2000 so I did not mind using what they provided if it was necessary.
