A few questions about engorgement after weaning?

My son weaned at 8 months. It took about 2-3 weeks for the engorgement to go away completely. Mostly because I expressed a little here and there to make myself a little more comfortable. The milk may leak, a little. It'll take 6-8 months for the milk to go away completely. I'm going on my 7th month, and I'm still producing a little. Except it looks more like colostrum, now.
