It is actually colostrum, milk does not come in till a few days after the baby is born. I started leaking I guess around 23-24 weeks. I find that I tend to leak more when the girls are left free, if I keep them in a bra, I tend to leak less. Warmth also seems to loosen the ladies up, after a bath or shower. I also leaked when I went to pick my DH up at the airport after he had been gone for 2 1/2 weeks. My midwife said it must have been a big release of oxytocine that caused the extra leakage.
