My baby girl only gained 8 oz from 5 weeks to 8 weeks. Shes exclusively breast fed and I thought we were doing well. She is now above average weight (11 lbs 12 oz) but was a big baby (8 10). Our pediatrician (new to us, we had a different doc with our first) wasn't concerned, but then I started researching a few days later and the numbers seem off. We'll call the doc on Monday but in the meantime, what do people think?
