Hospital bag - backpack or luggage

I just used my medium size gym bag. - baby onesie, swaddle, mittens, socks, hat - my dress, bra, panty - face wash, face cream, shampoo, soap for shower - toothpaste, toothbrush - phone charger things like maternity pads, hospital will provide. even the cooling pads are given. not a lot but it helps for the first few days. I ordered some after I got home. baby diapers and wet wipes also hospital provide. usually nurses would encourage breastfeeding. but for me my milk flow is still not in properly so my baby was on formula. I was KKH at that time they used GROW milk formula. they used small cups for baby to drink but can req for bottle too.
