I took Tesco maternity pads with me and they were great. Definitely size up on underwear ☺ They gave me my first couple of pads and then I needed to use my own.
They will give you all that at the hospital so I wouldn’t worry about packing any! But to have at home, I’d get the biggest ones you can. And maybe even the Always discreet underwear (sexy I know).
They won’t give you it here in the U.K. like in the US. They may give you one they did for me to go in the disposable knickers they gave me but other than that I used the lil let’s maternity and they were the best ones I got as they had wings xx
