preparation for essentials needs

Hi mommies.. i am currently 30 weeks and 6 days. I am a first time mom, ano ano po kaya essentials needs ni baby? Such as new born clothes, mittens,booties,pajama etc. Mga ilang sets po kaya ang kakailanganin ko? Ano sizes and saan po kaya makakabili ng maganda ang quality but not pricey? Thank you in advance.
