Milk production

Megan
When I started my son at 4omths with solids he began slowly only nursing 3 times a day on me.. I've been so busy that I didn't pump. Now it seems like my milk production is decreasing even more. I offer him to nurse about 6 times a day but he only wants to nurse maybe 4 times and not very long. He is fussy still at times after he nurses, so I've been trying to pump again and I've been taking Fenugreek pills 3 times a day. Any suggestions on how to increase my milk production? I've tried decreasing the amount of solids he gets and offer him to nurse more often but he seems to not want to.. (now my son is 6 months and 2 weeks old)
