Diaper questions (newborn)

Hi mummies! Would appreciate your advise on the following: For newborn diapers: 1. Should I stock up on NB Size or S Size for the first 1-2 months? 2. Diaper brand recommendations? *Preferably more pocket friendly since NB needs to change out frequently. 3. What’s the avg price for a pack of diapers/ per pc to be considered as cheap? Been seeing a lot of people selling on carousell and mummies groupchat but it’s either different pricing or different qty. #firsttimemom #advicepls #firstbaby #pregnancy
