Most of what's below came from primark
Button Down nightie - (skin to skin/if bf/easier than pyjamas in case of catheter )
Big knickers -
Warm socks.
Soft sports bra type crop top. (Rather than maternity bra's/easier to whack a tit out without fuss)
Baggy/comfy trousers - jersey material so could be worn as pj's or to go home.
Couple of strapped tops (h&m do my nice quality maternity ones. )
Baggy jumper/cardigan - for wearing home.
Slippers/cheap flip flops
boots
Water wipes.
Maternity pads.
Maternity puppy pads (much easier if you have a section/have a catheter in)
Flannel (multi purpose. Cold on head during labour. Used to wipe face etc after)
Wash bag - shower wash, GOOD QUALITY LIP BALM (I'm shouting that because I went through a metric fuckton of gas and air and my lips were insanely chapped the evening/ day after) brush/comb, bobbles. I took ear plugs/sleep mask (never came out of the bag, I was in one night)
baby
Water wipes are much easier and you've got these already.
Nappies
Baby bundlers (marks and spencer, SO much easier)
Few vests.
Blanket for in car seat. (Also, hat)
Familiarise yourself with car seat, they're tricksy as balls!
Towel
Charger
Plastic bag.
Earphones.
Snacks. Everyone says for during labour/your Dh. I was sick with every contraction and couldn't stomach anything while labouring, bugger your Dh, YOU need snacks for after! You may not get fed on the ward.
Fizzy lucoazade. Not the isotonic one. You need the sugar.
I had an EMCS and was only in 24 hours from operation to being discharged.
Good luck! Hope it all goes well!
