Store baby’s clothes for Infant Care

Hi mummies, for infant care bag, how do you usually store your baby’s clothes ? In a wetbag and label or just in ikea ziplock? And just bring another separate big wetbag for soiled clothes ? For extra clothes, the centre (sparkletots) is airconditioned and it states long pants preferred, what kind of clothes do you usually bring for them ? All long sleeve and pants? All sleep suits? Or some short sleep onesies? Since they wont be swaddled #firstbaby
