My one month old DS has only gained 80grams weekly (almost 3 ounces)
I feed on demand and hes been cluster feeding in the evenings, so theres not really much time in the day to feed him more because hes pretty much always on the boob?
Is there anything I can do to up the calories in my milk and get him to beef up a bit. Hes still not back at birth weight and hes a teeny 6lbs still 
If this is normal and Im freaking out, put it down to first time mum nerves! The midwife hasnt said anything but I havent been discharged from her care yet which makes me think they are quietly keeping an eye on it.
