I pump during the day and usually pump about 12 ounces. Lately I am lucky to get out 11. I am wondering if my supply is simply dimishing, or is it because the baby is going through a little bit of a growth spurt. He seems to be staying at the breast longer and sucking much harder. This means the milk runs out faster and he thinks there should be mroe. He has plenty of wet and poopie diapers. He is 20 weeks. I think it is his four month spurt, jsut alittle late. ANy ideas? Also I ahve already started taking fenugreek, blessed thistle and mothers milk tea.
