Perlu beli ke botol susu & breast pump?

Hi mommies, sy first time mom. Sy dah start beli brg2 keperluan baby dari skrang . Sy mmg plan nk breastfeed for the first 3 months. Then after that, akan masuk kerja. From newborn to 3months tu perlu tak sy beli botol susu & breast pump? Atau sy perlu beli yg 3m ke atas je terus? Setahu sy botol susu & puting baby are different according to baby’s age. Pls correct me if I’m wrong 🙏 #pleasehelp #firstbaby
