Don’t be stressed, you have so much time! I only finished preparing in my third trimester. Enjoy the process :)
Listing down what I’m using for my 3 mo little girl since birth :
Baby room: baby cot, storage for clothes, pjs, swaddle cloths, hankies, blankets, hats, mittens, booties
Baby bath time or cleaning: bathtub, shower gel, baby lotion, towels, baby nail clippers, tongue cleaner (optional), cotton wool, nappy cream, wet wipes
Baby feeding: milk bottles (quantity depends if u are breastfeeding or not. If yes and direct latching you will not need so many. If no, it will be easier to buy more so you don’t have to keep washing. Personally I have 4 bottles as I only do 3x bottle feed a day while the rest is direct latching),
sterilizer, bottle brush, breast pump, breast milk storage bags, pacifier (optional)
Others: stroller, car seat, baby gym playmat, diaper bag
For mommy: sanitary pads, disposable underwear, breast pads, nipple cream,
Hope this helps but try not to go overboard! You will eventually receive gifts or free gifts etc. ask away if unclear :)
