Vitamin D is necessary for its immune-boosting health, specifically bone growth after 6 months of age and thereafter; it helps with calcium and phosphorus absorption. Food alone cannot provide the source of Vitamin D that the body can use. This is why it is important to allow the skin to absorb sunlight.
The best times to enjoy the sun safely is before 10am or after 3-4pm. Ultraviolet rays are not at their peak during these times so getting some sunshine on a 20-minute walk at least twice a week is a good thing.
Walking around with a two-year old who loves to explore can be more easier with a kid leash. Brica By-My-Side Safety Harness Backpack was the only one I could find that was small and light enough for Josiah’s age. The leash is worn on a child’s back and attached to a parent’s wrist. There are several features which make this product unique for comfort and safety: there is a reflective safety strip on the backpack which keeps your child within view even at night; the tether is removable, so it can be worn as only a backpack later; the tether is shock-absorbent reducing strain from sudden tugs; and, a lot of storage space with a zippered main compartment.
