@Heather I only wear soft bras without underwire and thin padding. I stopped wearing regular bras years ago because I found them uncomfortable, digging into my ribs.
I have 4 from when I bf my first. Not planning on getting anymore. I did find the nursing strappy tops from h&m amazing and basically lived in them while bf.
I’m due next week and I think had a total of 5 or 6 nursing bras throughout pregnancy on rotation. Best advice I can give is to get a pack of bra extenders, in my third trimester I found they still fit my boobs but dug in around my ribs and didn’t want to buy a load of new bras the size up. I got a pack for £6 from Amazon with about 9 options for all styles/sizes and various colours and saved me having to buy a load of new bras
