@Aquablue1123, sorry but I had to laugh when reading this. Everyone feels the same about this. I'm sure I'll go through exactly the same thing again at some point and this is my 2nd.
Difficult to think of definite things as it depends how you plan on doing things and also how baby takes to things. It also feels like babies need a lot, but the majority of it is to make our lives easier (or feel easier) and depends on your preferences.
Basic things are:
clothes (simple for first 6 months: sleepsuits, vests, etc).
Food (breast/formula/bottles). Transport (carseat, buggy/sling,etc). Bed (moses basket/crib), sheets (a few for dribble/sick)
Nappies: a LOT, cotton wool/wipes, etc
Extra bits: muslins, steriliser (if expressing or formula feeding, can get elec/microwave/bags), hats (tiny heads needs to he kept warm when out), blankets, a mirror for the car is handy so you can see baby when they're in and facing backwards.
I recommend batch cooking as much food as you can before the birth. Buying lots of biscuits and easy to eat stuff. And some lovely bath/shower stuff as a treat for you when you need a bit of time out and to feel good again.
Any questions about anything feel free to ask and I'm happy to give my personal view point. Difficult to think of everything xx
