Hai D3 must till 1 year enough no need to continue Other medication can stop as of now If baby taking food well and active no need of supplements Please give all kind of food and in proper full nutrition way Without adding sugar and salt till 2 years of age (If needed in very small amount )

Greetings For a 1-year-old child weighing 8 kg who is consuming formula milk and regular solid foods, continuing all three supplements daily is generally unnecessary and introduces a substantial risk of vitamin and mineral overdosage. NAN Pro 3 formula and a balanced diet already provide baseline amounts of essential nutrients, so overlapping multiple multi-vitamin, calcium, and vitamin D3 drops can stress the infant's kidneys and risk toxic accumulation. Typically, routine Vitamin D3 supplementation is maintained up to 1 year of age, after which dietary intake usually suffices unless a specific deficiency is clinically documented. You should immediately discontinue this specific combination Check his vit d 3 level and hb and then plan to restart if required

Vitamin D upto one year age. Iron supplements and calcium can be continued. Baby taking formula feeds may not require multivitamin supplements. Baby is under weight for age. He requires nutritional supplements.

Consult with Pediatrician physically for further evaluation and treatment

Yes you can continue

At 1 year of age, if your child is taking age-appropriate formula milk and a balanced complementary diet, all three supplements are usually not required long-term. Vitamin D supplementation (400–600 IU/day) is commonly continued in toddlers, especially if dietary intake and sunlight exposure are inadequate. Routine calcium supplementation is generally not necessary unless dietary calcium intake is insufficient or there is a specific medical indication. Similarly, multivitamins are not routinely required in a healthy child with adequate nutrition. Since formula milk already contains vitamins and minerals, continuing multiple supplements may lead to unnecessary excess intake over time. I would advise discussing your child’s growth parameters with your pediatrician and simplifying supplementation accordingly. Also, a weight of 8 kg at around 1 year is on the lower side and should be interpreted along with birth weight, length/height, head circumference, and growth chart trends. A growth assessment by your pediatrician would be helpful
