We feed our 4 month old son every 3-4 hours 5 times in 24hrs and hes on 7oz 210ml each feed. Is that enough? Hes always fine after a feed never asking for more or showing sings for more so I assume he's full and I always give it to him when hes showing signs even if its early. Hes growing and putting on weight its just my husband keeps saying its not enough and he should be on like 7 feeds in 24hr? Can any help?
