Hello. I can understand how scared you must be feeling. Dosage error can happen with any parent, so don’t blame yourself. Don’t administer any more doses until a physical consultation is done. It is a high dose, but not enough to be toxic. Will need to check baby’s weight and other symptoms if present to be completely sure. If there are no symptoms and baby has gained adequate weight, it should be alright.

1200 iu daily exceeds the normal dose. Does your baby have any symptoms?? Like vomiting, poor feeding, lethargy?? If your baby is growing well and has no symptoms, switch back to 400iu daily asap. Consult for further information.

Dont worry

If the baby did not have any symptoms then nothing to worry. 400 IU is only required dose.

Watch for Vomitings and abdominal pain and constipation. Stop medicine for few days 5-7 days . Give vitamin d3 drops 400 iu once daily till 1 yr of age .

No issues if child is otherwise active and feeding adequately Give only 0.5 ml once daily

No worry

Required dosage was 0.5ml daily once in this strength . Vitamin D drops is coming in n2 concentrations .one ml contain 409Iu 0/ containing 800IU / ml . Kindly always check medicine strength and dosage before administering. If in doubt you can always consult a doctor . now please stop medication. Can attend a nearby paediatrician for check up of the baby

Dont worry for just 3 days it will not cause any problems

Greetings Look for a warning sign for any vomiting any abdominal discomfort If any visit doctor immediately Or else skip vit d for 3 days and then restart
