Low Production

Tori
I bottle and bf but my supply is going down. LO is 3mos and I want to bf until 6mos. She is now taking 3.5-4 ounces on a bottle but she cries and pulls away at about 8 mins in when bfing like I ran out before she was full. I'm trying moms milk tea, pumping after feelings and lactation cookies. Any other ideas? I don't want to dry up and I'm running low on my frozen supply.
