Carlson - Baby's Super Daily D3, Baby Vitamin D Drops, 400 IU (10 mcg) per Drop, 1-Year Supply, Vegetarian, Liquid Vitamin D for Infants and Toddlers, Unflavored, 365 Drops

Carlson Labs Baby’s Super Daily D3 is a convenient and reliable way to ensure that your baby is getting supplemental vitamin D. The product comes in a small bottle that lasts for a whole year with daily usage, and only a single drop is needed per day. The pediatricians recommend it, and the vitamin D is from lanolin (sheep's wool wax) from New Zealand. However, the packaging and the bottle's design can be problematic as it’s not easy to dispense just one drop. The drop takes a while to come out, and the bottle leaks if it's put on its side. Some customers use it by dropping it on a bottle nipple, their fingers, or other surfaces and letting the baby suckle. But, it's not easy to put it directly on top of the baby's mouth since kids move so much. Some customers recommend the manufacturer modifies the packaging to make it more user-friendly, perhaps a dropper or a squeeze bottle, but this problem seems to be common among most vitamin D supplements.
