In mine I put:
A pack of cards/ something to entertain me in case labour was long
The small pack of nappies think you get about 20 in a pack (I had more than enough there but I wasn't there 24 hours)
2 packs of baby wipes (I only put one but meconium is sticky & really hard to clean
)
A couple of vests and comfy clothes for baby (something that's just easy for you to whip on and off them)
Blanket for baby
Travel size shower kit
Essentials like deodorant, toothbrush toothpaste (I'd prob pack face wipes & deodorant wipes so you don't have to keep getting up and down to wash because you might feel manky but you'll prob feel too uncomfortable to keep getting up)
Not sure if hospital provided but I took my own bath towel
A box of maternity towels
A few pairs of old knickers
A couple of nighties that were buttoned at the top so I could breastfeed easily
(Formula if you're not breast feeding)
Dressing gown
Slippers
CAMERA, phone charger, iPod etc
Snacks, I found myself eating fruit pastels at 3am (well deserved haha)
A going home outfit for you & baby
I think, that's about it I'll post again if I've forgotten :)
