Congratulations on your May baby! For KKH, I'd pack comfortable clothes you can change into straight after delivery (something pre-pregnancy size, trust me), toiletries, underwear you don't mind throwing away, phone charger, and a few newborn outfits in different sizes since you won't know how big baby is. I also brought snacks my husband could grab between visiting the canteen, extra pillows from home in coloured cases so they don't get mixed with hospital ones, and my own towels. KKH provides most things but having your own makes the stay feel less clinical, especially during the first few nights when you're adjusting.
