My favourite things that I packed were:
My water bottle with a straw (got a MANGO bottle from Amazon) it was literally a life saver during a long labour! My husband could get me a quick sip between contractions and didn't have to move positions etc. No leaking either.
I also loved having some simple face wash, but for use on my whole body. I knew it was super gentle so although I had no interest in washing down there (due to stitches etc) I wanted to know anything I used elsewhere wouldn't run down my back and irritate things.
A big comfy scrunchy for my hair was nice. Something you know sits nicely when lay down etc.
Really large high waist knickers from M&S... way more than you think. I used my entire pack before baby even came cos my waters went everywhere throughout the first day in hospital. Had to send my mum out for more. You will wear them post partum too so it's worth it.
Definitely some large comfy maternity bras. I was caught short there, everyone said I would want to wait and see/get measured when milk came in but trust me you need them ASAP. I got great ones from Amazon in the end that I highly recommend, only come in S, M, L so not real need for measuring etc.
Phone charger with a very long wire.
I love idea of white noise machine for hospital that's great, we used iPhone but wasn't convenient at allll. Also possibly a night light. The Dream Egg is great and does both. Highly recommend that.
Don't forget your nipple cream!
Also pack babies outfits into individual bags ready and labelled by size. I found that helpful. We took 3 outfits in newborn/first side and 3 in 'up to 1 month' and wished we hadn't bothered with newborn cos he was big but I also didn't want him to be swamped in his first photos so maybe do take a couple of newborn just in case. He was a big baby! 0-3 would be too big for any baby I reckon (unless from a shop that comes up small?) so probably wouldn't bother with that if you want the clothes to look well-fitted.
I wish we took a little wooden 'welcome to the world' thing or something similar. Maybe something with the name on if you know what it's gonna be!
Own pillow is a good shout. Ear plugs also are essential as the noise of people pressing the buzzer was horrendous, all night long!
Plenty of nappies to give yourself chance to do them wrong etc. Also a larger hat in case baby has a big head. Ours did and not one hat that the hospital provided fitted him bless him!
Good luck!! 😀❤️ it's a great experience!!
