Is it normal to worry about fat at this age?
Yes. Babies need a higher fat proportion than older kids or adults because the brain grows fastest in the first 2 years.
It is normal if your 6 to 12 month old prefers richer foods. Do not choose low fat products for babies unless your clinician advises it.
Breast milk and standard infant formula already supply substantial fat. Complementary foods add variety and key fatty acids.
Why fat is critical in the first 2 years
- The brain is rich in lipids by dry weight. Rapid myelination from about 6 to 24 months needs fat, especially long chain omega-3 and omega-6 (DHA and ARA).
- Fat provides concentrated energy for small stomachs and helps babies meet needs without oversized portions.
- Dietary fat enables absorption of fat soluble vitamins A, D, E, and K that also support vision, bone health, and immunity.
- Essential fatty acids (linoleic acid, alpha linolenic acid) cannot be made by the body and must come from food.
- Guidelines from ESPGHAN and AAP advise against restricting fat in children under 2, with targets around 35 to 45% of energy in late infancy.
How to prioritize smart fats day to day
Hit age appropriate fat targets
From 6 to 12 months, aim for about 35 to 45% of energy from fat (ESPGHAN). From 12 to 24 months, about 30 to 40% (AAP). Practically, include one higher fat food at each meal and add 1 to 2 teaspoons of oil, nut butter, butter, or avocado to boost energy if needed.
Cover essential fatty acids
Adequate Intake for 7 to 12 months: linoleic acid (LA) 4.6 g/day and alpha linolenic acid (ALA) 0.5 g/day; for 1 to 3 years: LA 7 g/day, ALA 0.7 g/day (IOM/NASEM). Foods: oils (canola/rapeseed, soybean, walnut), nut butters thinned, ground flax or chia, tofu, and fatty fish.
Aim for about 100 mg DHA per day on average
Expert groups such as EFSA support 100 mg/day DHA for 6 to 24 months. Offer oily fish 1 to 2 times per week (salmon, sardines, trout, Atlantic mackerel, herring). Portion for babies is small: about 1 ounce once or twice a week. Choose low mercury options and flake well for bones.
Keep breast milk or formula central in the first year
Both provide major fat and, in the case of most formulas, DHA and ARA. If breastfeeding, maternal DHA intake of about 200 to 300 mg/day helps enrich milk (AAP/WHO). Baby DHA supplements are usually unnecessary when breastfed or when using DHA containing formula unless your clinician advises otherwise.
Choose whole fat dairy at the right time
Offer full fat yogurt or cheese as complementary foods after 6 months. Do not use cow’s milk as the main drink before 12 months. From 12 to 24 months, AAP and NHS recommend whole milk dairy unless advised differently for a medical reason.
Use heart smart oils and avocado
Cook with olive or canola/rapeseed oil and drizzle 1 to 2 teaspoons on warm foods like veg, beans, or grains. Serve 1 to 2 tablespoons mashed avocado often. These provide monounsaturated fat and vitamin E.
Serve nuts and seeds safely
Never give whole nuts to babies. Instead, thin 1 to 2 teaspoons smooth peanut, almond, or cashew butter into yogurt or porridge, or use finely ground nuts. Add 1 teaspoon ground flax or chia to oatmeal for ALA. See our allergen guide before first exposures.
Include eggs several times per week
Eggs contribute fat and choline for brain support, and some are DHA enriched. Serve well cooked scrambled or mashed pieces. Early introduction also helps with allergy prevention planning.
Vegan or fish free families
Prioritize canola/rapeseed, soybean, and walnut oil; peanut or other nut butters; tahini; tofu; soy yogurt; ground flax and chia. Talk with your pediatrician about an infant algal DHA supplement to reach about 100 mg/day if oily fish and eggs are not used.
Simple plate ideas
Oatmeal mixed with full fat yogurt + mashed berries + 1 tsp ground chia. Scrambled egg in olive oil + avocado + soft toast fingers. Lentils with carrots + 2 tsp olive oil + dollop of yogurt. Flaked salmon + mashed sweet potato + peas with a pat of butter. For more inspiration, see our first foods guide.
What to limit or avoid
Avoid trans fats (ingredients listing partially hydrogenated oils). Do not default to low fat products under age 2. Coconut oil is fine in small amounts, but rely more on olive and canola/rapeseed oils overall.
When to call the doctor
- Poor weight gain, feeding fatigue, or very small portions with little visible fat in the diet.
- Dry, scaly rash, brittle hair or hair loss, and slow growth that may suggest essential fatty acid deficiency.
- Pale, bulky, or greasy stools, foul smelling diarrhea, or oil droplets in stool that may indicate fat malabsorption.
- Signs of fat soluble vitamin issues: easy bruising or bleeding (vitamin K), bowing of legs or delayed milestones consistent with rickets (vitamin D), or night vision problems (vitamin A).
- Developmental regression, significant feeding aversion, or suspected swallowing difficulty.
- Multiple food allergies limiting fat sources, vegan diet without DHA planning, or a history of prematurity or chronic gut/liver disease.
Frequently asked questions
How much fat does my baby actually need?
From 6 to 12 months, about 35 to 45% of calories from fat is appropriate (ESPGHAN). From 12 to 24 months, 30 to 40% is recommended (AAP). You do not need to count every gram. Offer a high fat food at each meal and use small additions of oil, avocado, nut butter, or butter to meet needs.
Which oils are best for cooking for babies?
Olive and canola/rapeseed oils are versatile and provide healthy unsaturated fats. Soybean and walnut oils add omega 6 and some plant omega 3 (ALA). Avoid trans fats and limit reliance on coconut oil, which is mostly saturated fat.
Do babies need DHA supplements?
Usually no if they are breastfed and the breastfeeding parent consumes DHA regularly, or if they take a formula with DHA and ARA. EFSA suggests 100 mg/day DHA for 6 to 24 months, which can be met with 1 to 2 small servings of low mercury oily fish per week. Vegan or fish free families can ask about an algal DHA supplement.
What are safe fish choices and how much?
Low mercury oily fish like salmon, sardines, trout, and herring are good. Offer about 1 ounce once or twice per week for babies. Avoid high mercury fish like shark, swordfish, king mackerel, marlin, tilefish, and bigeye tuna. Check local guidance for specific species.
Should I use low fat dairy for my 1 year old?
No, not by default. AAP and NHS advise whole milk dairy from 12 to 24 months unless a clinician recommends otherwise for specific health reasons. Before 12 months, use breast milk or formula as the main milk and offer small amounts of full fat yogurt and cheese as complementary foods.
Are saturated fats bad for babies?
Babies can have some saturated fat from foods like dairy and meat, but most fats should be unsaturated from oils, avocado, fish, nuts, and seeds. The overall pattern matters more than any single food.
How do I meet essential fatty acid needs on a plant based diet?
Use canola/rapeseed, soybean, and walnut oil in cooking; add 1 teaspoon ground flax or chia daily; serve thinned nut or seed butters. These cover LA and ALA targets (about 4.6 g LA and 0.5 g ALA for 7 to 12 months). Discuss an algal DHA supplement to reach about 100 mg/day if no fish or DHA enriched eggs are used.
Any choking risks with high fat foods?
Yes. Avoid whole nuts and large globs of nut butter. Thin smooth nut butters into yogurt or spread thinly on soft bread and cut into small pieces. Flake fish carefully for bones. Cut cheese into very thin strips or melt into foods. Always supervise meals.
