My ds is putting on weight but slowly so dropping through centile lines (born on 50th now below 2nd at 11 weeks). HV suggested I have low supply coz I'm so busy with 2 other children. Don't have much time for their opinions normally, but wondering about what I can do to up my supply, as I have to agree that although it was fine up until now, it's getting to the point now where he does seem dissatisfied straight away or quite quickly after feeds later in the day. Any thoughts?
