so my baby is having way more milk than usual, he usually has about an ounce an hour (3 ounces roughly every 3 hours) he is mixed fed so i am aware some feeds will be closer together due to breast milk being digested quicker, but he has had about 7 ounces in the last 4 hours!! he is clearly hungry for it and isn't sick after it. can u over feed a baby or should i follow what he wants? tia x
