🔍 Possible Causes:
Overdosage
Vitamin D toxicity can occur if the dose is too high (especially >1000 IU/day for infants unless prescribed).
Symptoms: vomiting, poor appetite, constipation, increased thirst/urination, and irritability.
Gastrointestinal irritation
Some babies have sensitive stomachs, and Vitamin D drops may irritate the stomach lining, especially if given on an empty stomach.
Allergic or intolerance reaction
Rare, but some infants may react to components in the drops (like flavorings, preservatives, or the oil base).
Coincidental illness
The vomiting might be unrelated and due to another issue like a viral infection, indigestion, or reflux.
✅ What You Can Do:
Check the dose
For infants: usually 400 IU/day is recommended.
Confirm you're not accidentally giving more.
Give after feeding
Try giving the drops after breastfeeding or formula feeding to reduce stomach irritation.
Temporarily stop and observe
Stop the drops for 2–3 days and monitor if vomiting resolves.
If yes, it's likely related to the drops.
⚠️ See a Doctor If:
Vomiting is persistent, severe, or associated with:
Lethargy
Poor feeding
Dehydration (dry mouth, reduced urine)
Weight loss
