Icy - Even subsequent months, I hardly use any coz at work, will express every few hours. If go out, unless you don't bring baby or you stay out for couple of hours (say 4hours), then the breasts will become very full and may leak. Other than that, can always express at home or feed baby direct. But of coz up to individuals. You may wanna buy more once after you assess your own situation. Coz I realise a lot of moms try to sell their excess pads in the forum coz over-estimate and bought too many.
