Breastfeeding is undoubtably one of the best things you can do for your newborn when it comes to nutrition. Breast milk is high in proteins, fats, amino acids, most vitamins, minerals, and antibodies that protect your baby from infections and illness. But the one nutrient that breast milk lacks is vitamin D, which is crucial for the development of healthy bones, teeth, and muscles.

Not enough and a baby can develop rickets, an ailment that softens the bones’ growth plates which can result in physical deformities like bow legs. Sunlight is a good source of vitamin D, but it is not safe to have baby outside without sunscreen, which blocks the body’s absorption of this important nutrient. Luckily, it’s easy to correct this deficiency, and all you need is  a vitamin D-rich supplement, like Super Daily D3 for Baby by Carlson Labs.

Each drop of this D3 liquid formula contains 400 IU of vitamin D,  the daily recommended dosage from the American Academy of Pediatrics. It’s so easy to administer: Simply turn the bottle upside down and wait for a drop to dispense (it doesn’t happen right away, so be patient!). The liquid is colorless, odorless, and tasteless and can be mixed with your baby’s food or even placed on a pacifier. As a bonus, Super Daily also contains vitamin E and is free of sugar, gluten, preservative, and any sort of artificial colors or flavors.  A single bottle lasts an entire year, so once you buy it, you don’t need to worry about it again – by the time those first 365 days are up, your child will be eating more solid foods which usually have enough vitamin D for a strong little body that’s full of life!
