Ds is now 5.5mo. He has always being big, was 8lb3 at birth. He has always being in bigger clothes for his age. He is in 6-9mo tops, and 9-12mo bottoms. (Can never buy a matching outfit !!). HV was concerned last time he was weighed as he has gone from the 91st centile to the 98th. He is a very hungry baby and is already on solids (from 5mo), as well as hungry baby milk. Is there anything I can do? Overall he is very healthy and happy but HV being concerned has worried me.
