When did your boobs start leaking...A LOT?

Bárbara • I'm 29, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!
I started leaking at 21w, it's usually just some drops and sometimes one boob and sometimes the other, but today (23w6d) I've been leaking all day and from both boobs, is this normal? When did you start leaking a lot? Btw, should I buy pads? Thanks ^^
