Look up newborn necessities! There's tons of lists to help you! With my first i did that and organized it in the baby registry app called babylist, so I knew what I or other people bought! It was super helpful with all the overwhelming things to buy!
Nappies Wipes Changing mat Bepathen Clothes: Babygrows Vests/bodysuits Cardigans I wouldn’t recommend buying too much new born size because you may find they outgrow it quickly or don’t get to wear it at all and you can always buy more once they’re here if needed Scratch mittens Hat Somewhere to sleep- cot or next to me, somewhere baby can sleep for day time naps Fitted sheets and waterproof mattress cover Sleeping bags Baby towels Car seat Push chair Blanket Changing bag Muslim squares If breast feeding: nursing bras breast pads nipple cream If formula feeding: bottles with teats and caps sterilising equipment brush to clean the bottles and teats formula milk powder or ready-to-feed liquid formula I bought the small ready to feed bottles with teats and had them in my hospital bag worth having even if you’re planning on breast feeding just incase
