Hi! It can take as long as you haven't nursed to regain full supply. So if you haven't nursed in 3 months, it may take that long for full supply to come back.
And no you arent crazy! I haven't nursed my DS is 5 months! Things are going great! It's a slow slow process so don't expect anything over night.
You should pump every 2-3 hours for 15-20 min, not 8-10. Milk supply is all about demand. The more demand, the more milk your body will make.
I hope all goes well! Keep us updated!!
