Congratulations! Those with warranty and expiry dates can wait till last trimester/2 weeks before EDD. Eg sterilizer, breast pumps, detergents, wet wipes etc etc. Clothings/strollers/car seats/cots and carriers etc can browse first, go down to mummy market/baby fairs to try out and see the actual product then camp for sales. I find usually shopee/lazada with stack on vouchers sometimes cheaper than baby fairs. To save further more, can request hand me downs clothings from your friends or Carousell as they outgrow quite fast :).
2nd trimester around 5-6months after knowing baby gender. This was when I strat slowly buying baby stuffs and 3ventually preparing diaper bag for when I have to go hospital. They say 2nd trimester is the best cause you no longer have nausea and your body feels stronger and energetic, unlike 1st and 3rd trimester
best time is after finding out baby gender
