best to get 1 hospital grade pump there's a difference in supply. the bottles depend on whether it can fit your pump. and you do not need to buy the same brand milk bottle. will recommend you to get spectra s1 from qoo10. bottle pigeon recommended to prevent nipple confusion. if you need any help feel free to DM me @mummyjlife IG
horigen brand from ourlittlelamb.com comes w convertor to fit 90% of milk bottles.. their are cost effective too :)
