Im not sure if I should be concerned. I breastfeed DD who just turned 6 mo. I started feeding her solids about 4 weeks ago. She eats a little bit of solids maybe once a day, sometimes just BFs. She hasn't had a BM in 9 going on 10 days. She doesn't act like she's in discomfort, in fact she's a very happy, tough baby. Doesn't cry for much. When should I be concerned about her BMs?
