How early do you start buying baby items?

Will it be too early if i start buying baby items now? My edd is 20 April, which is 8-9 weeks away from now. And so far ive onlu bought the baby cot because it's on sale during the CNY period. I dont want to only start buying it a month before the edd, because it will be tiring since will need to spring clean the room and at the same time it will be fasting period as well. But i scared it's still early to buy it. Help me! Hahah
