0:00 Babies who regularly ate peanut products starting around four to six months were eighty-one percent less likely to develop a peanut allergy.0:09 That finding comes from a landmark study that completely changed how we think about feeding our little ones.0:17 Last week, in our episode on teething, we talked about the signs your baby is ready for solid foods.0:24 Today, we’re talking about what to feed them, especially the foods that can feel the most nerve-wracking: the common allergens.0:33 For decades, the advice parents got was to delay introducing foods like peanuts, eggs, and dairy.0:40 The thinking was that waiting would protect them.0:43 But the science now shows the exact OPPOSITE is true.0:47 There seems to be a critical window, usually between four and six months of age, where your baby’s immune system is learning what’s safe and what’s not.0:58 When you introduce these allergenic foods early and often, you’re essentially training their body to recognize them as friends.1:07 You're building tolerance.1:09 Here’s what we think is happening.1:11 For some babies, especially those with eczema, their first exposure to an allergen might not be through food.1:19 It might be through tiny particles in the environment that get in through their broken skin.1:25 Their immune system sees it as an invader and gets primed for a fight.1:30 But when you introduce that same food through their mouth first, their gut teaches the immune system that this is just food, not a threat.1:40 Now, I know this can sound scary.1:42 If you're feeling hesitant, that's completely normal.1:46 In fact, studies show that fewer than twenty percent of parents introduce peanuts before seven months, mostly because of fear and confusing advice.1:56 But the evidence is now overwhelmingly clear.1:59 So how do you actually do this safely?2:02 First, make sure your baby is showing signs of readiness for solids, which we talked about last week.2:09 They should have good head control and be interested in food.2:14 And this is important: never start before four months old.2:18 If your baby has severe eczema or an existing food allergy like an egg allergy, talk to your pediatrician before you begin.2:26 They are your best partner in this.2:29 When you're ready, introduce ONE new allergenic food at a time.2:33 Then wait two or three days before introducing another new one.2:38 This way, if there is a reaction, you’ll know what caused it.2:42 For peanuts, you can mix two teaspoons of smooth peanut butter with a little warm water, breastmilk, or formula until it’s a thin, runny puree.2:52 You can also use peanut powder and mix it into a fruit puree your baby already likes.2:58 Never, ever give a baby whole peanuts or thick gobs of peanut butter.3:03 For eggs, offer a small amount of well-cooked, scrambled egg.3:07 For dairy, a spoonful of plain, whole-milk yogurt is a great start.3:12 And here’s the key: keep going.3:14 This isn’t a one-and-done test.3:16 The goal is regular exposure to maintain that tolerance, so aim to include the food in their diet a couple of times a week.3:25 Of course, you need to know what to watch for.3:28 A mild reaction might look like a few hives around the mouth.3:33 More serious signs include swelling of the lips or face, vomiting, widespread hives, coughing, wheezing, or any difficulty breathing.3:42 If you see those serious signs, you need to seek immediate medical attention.3:47 The good news is that severe reactions are not common, but every parent should be prepared.3:54 So what does all this add up to?3:56 It means we’ve shifted from a strategy of avoidance to a strategy of early, safe introduction.4:03 You're not just feeding your baby; you're actively helping their body build a strong, tolerant immune system for the future.4:11 This week's science gives you a powerful tool to help protect your child, one tiny, thinned-out spoonful at a time.
