Hi mummies, today is my 4th day after delivery, however the milk hasnt kicked in. Unlike my #01, milk came in on day 1. Breast is very soft. What can i do?

my milk supply kick in after day 7... though i tried latching, there was like nothing for her to drink & i was discouraged by ppl ard me. then i tried using the pump i bought, and somehow the supply came in after a week.
