want to breastfeed

Hello! FTM po, expecting at 21 weeks. Can this be a help po? I want to breastfeed my baby kasi. Nakita ko lang to sa vlog ni Kryz Uy sa Youtube sabi nya big help daw yung breast warmers pero ibang brand yung gamit nya. Any moms who have tried this? Ano po feedback nyo, how was it po? Thanks mommas!
