Pjs and nighties - primark. £3 for granny stylee but good for nursing, £3 for v soft bottoms, £3.50 for beautifully sift nursing pj vest. That's what I bought today amongst shit loads of other stuff!
Hospital bags don't need half as much stuff as websites tell you you do. Change of clothes for you, couple of nighties/pjs, toiletry bag (although my hospital insists you use their steriliser shower gel so don't go mad in case your hospital is the same), snacks for you and dh, camera, phone charger, change for car parking and vending machine/coffee shop. For baby, three or four vests and sleepsuits, cellular blanket, hat, nappies, scratch mitts, water wipes.
