HELP PLEASE

Katie • Wife,Mother of 3
So little back story. From the day our son was born he was exclusively breast-fed we made it to three months only to hit that Growth spurt then and my supply went down tremendously it took over 48 hours before I even had enough milk again by this time my son was on bottles and did not want to latch anymore I was devastated fast forward to now my son is nine-months-old and is showing interest in my breast to again. He has tried to latch on many of times but can't seem to figure it out now one-sided produces milk maybe 5 to 10 drops and that's it I've tried letting him latch on his self to see if you can get that out it doesn't work I have hand express the milk I do have out and let him latch on that way and it helps a little but we still can't seem to get it to latch back on so my question is how do I go about getting my milk supply back up and how do I help my son learned to latch again I would love to be able to breast-feed again now I do not own a punp my body did not respond to the pump so it was useless
