Even so, when my first baby was hard to settle after a feed, and my midwife ruled out latch and supply issues, she suggested I cut back on dairy—scientific proof aside. I tried it for a few months and noticed a difference. “Cow’s milk protein can be hard to digest,” says Anita Arora, a lactation consultant in Milton, Ont.
Keep a food diary to help you figure out if there’s a pattern. (It can take two weeks to eliminate cow’s milk protein from your system, and note that lactose-free products are not necessarily free of cow’s milk proteins.) You may be able to phase dairy back in after a while—some babies outgrow their sensitivity by six to 18 months.
