Hello, My DS is 17 months old and preverbal. We do Baby Signs to communicate. In the last 2 weeks or so he will sign "milk" "more milk" while nursing, sometimes crying. He is taking both sides which he has not done in months. I offer both then the first again. Now in the last 2 days he is nursing for a much shorter periods of time. I thought I might be preg but the test says no. Any other ideas? Thanks!
