My son, who is exclusively bf has gone from 25th centile to 9th centile on the growth chart over the last 8 weeks. I've been very relaxed (maybe too relaxed) about weighing him assuming all is fine because he seems so well. Today was the first time he was weighed in almost 8 weeks. I wasn't surprised to see he's small but the change worries me a bit. The GP suggested weighing him again in a couple of weeks.
Should I be concerned? Any experience of similar? Could it be that I'm not feeding him enough or even that there's not enough milk for his needs? He doesn't seem dissatisfied though he has been spending longer on the breast lately.
Any tips?
