All normal. Perhaps time to try out breastpads if it increases?

Mine are not leaking exactly but this time around I've felt a let down sensation and later discovered that the centre of my nipples has a white substance that is dry and crumbly. I've squeezed to see if anything comes out and a few tiny shiny beads will show. So, my colostrum is in too but not as flowing as yours. At least you know your supplies should be good when bub arrives, with my firstborn it took a while to come on.
