buy washable breast pads.
i used to leak a lot. i can change pads about 4-6 times a day!
how often do you pump? because let's say if i'm pumping every 5 hours, and my breast leak increasingly when it gets closer to the next pumping session. so what i do is i put breast pad for the first 4 hours, and at the last hour, i replace with breast shell. the maximum i'm willing to let the milk stay inside is 1 hour.
i realise that after an hour the milk tends to start separating itself and i dont't feel that the milk is fresh after that. just a personal dislike. haha!
sometimes i feel that if the leaked milk is not collected, it would be wasteful. but i realise that the leaked milk is the foremilk and are not as nutritious as the hindmilk. so i reasoned myself this and i dont't feel so painful for not collecting it.
