Congrats OP! I’m pregnant too (2nd time round this time) and here is my list.
For me - 4 pairs big black knickers, a big dark towel, hair towel wrap, bobbles, hairband, maternity pads, breast pads, 2 pairs maternity or big leggings and 2 big comfy tops, 3 maternity sleep bras, 2 very loose nighties, a pair of slippers, a pair of flip flops, nipple balm, shampoo, conditioner, shower gel, moisturiser, toothbrush and toothpaste, lip balm and peppermint tea (helps with trapped wind if you need a C-section) oh and a few snacks - dry roasted peanuts and hobnobs were my go to last time despite having endless options of snacks. I also took loads of socks last time but only wore socks to come home as it was so hot all the time! So I’m only taking 1 pair of socks.
Then for baby - a pack of size 1 nappies, 2 packs wipes, 4 muslins, 4 sleeveless vests, 1 cardigan, 4 sleep suits with 1 to be a bit fancier than the others as a ‘going home outfit’, 2 cellular blankets and a little hat (only taking size 0-3 months - my last baby was huge and didn’t fit in any newborn stuff I’d got for her plus bigger is comfier anyway!) I didn’t take a dummy last time as I thought it would interfere with breastfeeding but I will be taking one this time as it helps settle baby and I’ve breastfed for 14 months.
