Yes — Mumry-D3 Drops (vitamin D3, cholecalciferol) are generally safe for a teething baby when given at the dose recommended by your paediatrician.

⚕️ What this means

• Mumry-D3 Drops provide vitamin D3 to support calcium absorption and bone health; teething itself does not make vitamin D unsafe.
• Use only when prescribed or recommended by a paediatrician and following their dose for your baby.

💊 How to give & precautions

• Follow the exact dose and frequency your paediatrician prescribes; do not add other vitamin D supplements unless told to.
• Give with a small feed or breastfeed/formula as advised (fat helps absorption).
• Watch for common side effects listed for the product: constipation, vomiting, or poor feeding — these usually resolve but should be reported if persistent.

⚠️ When to seek urgent care

• Go to emergency care or contact your paediatrician immediately for persistent vomiting or refusal to feed, very low urine output/dehydration, or extreme drowsiness or seizures.

🩺 Next steps

• Confirm the correct dose with your paediatrician before starting or continuing the drops.
• Tell your paediatrician about any other supplements or medicines the baby is receiving.
