What are the best, most essential baby products for new parents?

It was the luckiest and happiest moment in my life when I got my baby last month, I bought all new baby essentials like blankets, thermos bottle, diapers, and furniture items and many things through My 1st Years Discount Codes , I already planned it 4 months before that I will buy all their baby essentials.

Some material things might help as well, other than obvious ones like diapers, furniture etc.

1. Swaddle blankets - I bought them way too late, they would help me so much if I had them from the start
2. A thermos bottle with warm water next to changing table - for wiping baby/ your hands/ the table
3. 1000 pillows. Or a nursing pillow. But a few 50x25cm pillows work better, and they are usable afterwards.
4. Glass watter bottle (from Voss water or similar) on every surface in the flat - breastfeeding makes you thirsty and water should be accessible everywhere and always.
5. Washable nursing pads. They are way better (and long-term cheaper) than single use one.
