Mommies help me. I'm trying to build my milk supply again. It's been about 4 weeks since I've pump or fed off the boob. I can hand suppress a little milk but I need to produce more. The formula isn't working for my baby no more. I give him breast milk I have frozen every now and then to clean his system. PLEASE HELP. I'm trying to pump again but I'm not getting anywhere. I'm also taking milk thistle tablets.
