My 7 week old baby girl seems to prefer little and often feeding. She's fed on Hipp Organic Formula, and varies from 1.5 oz, 2oz maybe 3.5oz each feed and will do this every 2 hours. HV says she's consuming the correct amounts for her age and weight. Just wondering if there's anything I should be doing or if this is normal? On advice from the HV we have recently changed to bigger teats which has helped her become less restless and she now sleeps on her back!
