Can a 3-Month-Old Baby Take Ikexin Vitamin AD Drops and Star Shark Vitamin D Drops (400 Units) Together?

Is it safe for a 3-month-old baby to take both Ikexin Vitamin AD Drops and Star Shark Vitamin D Drops (400 units) simultaneously? The doctor recommended that my baby take one Ikexin Vitamin AD Drop in the morning and one Star Shark Vitamin D Drop in the evening. Is this method excessive, as it’s generally recommended to take only one type? I’m considering alternating the doses, taking one type each day. Is this okay?
