Vitamin D for Babies

ALL babies need vitamin D — whether breastfed or formula-fed. In northern latitudes, there isn't enough sun to produce adequate vitamin D through the skin, especially not through baby skin that shouldn't be in direct sunlight. Vitamin D is essential for bone development and the immune system.

Causes Possibles

  • 1Low UV radiation in northern latitudes (e.g., central/northern Europe: virtually no vitamin D synthesis October-March)
  • 2Baby skin must not be in direct sun (sun protection and shade prevent vitamin D synthesis)
  • 3Breast milk contains only small amounts of vitamin D (regardless of maternal intake)
  • 4Darker skin: more melanin blocks UV radiation more strongly → higher deficiency risk

Ce Que Vous Pouvez Faire

  • 400-500 IU vitamin D3 daily — from week 1 of life, EVERY day, all year round
  • Drops or tablets: give before breastfeeding/bottle — dissolve on the tongue or in a little milk
  • Continue supplementation until at least 12-18 months, then discuss individually with paediatrician
  • Premature babies: higher dose (800-1000 IU) as recommended by the doctor
  • Vitamin D is available as drops (easiest for babies) or tablets to dissolve

Quand Consulter un Médecin ?

  • Signs of vitamin D deficiency: restlessness, head sweating, delayed motor development
  • Rickets: soft skull bones, delayed fontanelle closure, bowed legs, widened wrists → see doctor IMMEDIATELY
  • Increased susceptibility to infections may indicate vitamin D deficiency
  • Baby consistently refuses drops/tablets → discuss alternative form with doctor

Notes Selon l'Âge

From week 1 of life: start vitamin D (regardless of breastfeeding or formula). Until the 2nd spring: daily supplementation recommended. After that: decide individually based on lifestyle, skin colour, and sun exposure. Year-round: supplementation is recommended throughout the 1st-2nd year, as even in summer sun exposure is insufficient for babies. IMPORTANT: Formula milk does contain vitamin D, but the amount isn't always sufficient — supplement according to medical advice regardless.

Questions Fréquentes

Does my baby need vitamin D even though they drink formula?
YES. Formula is fortified with vitamin D, but most paediatricians still recommend supplementation as the amount in formula may not always be sufficient depending on intake. Discuss the dosage with your paediatrician.
What's better — tablets or drops?
Drops are easier for most babies to take. Tablets can dissolve on the tongue or be dissolved in a little milk. Both forms are equally effective — what matters is that your baby actually gets them.
Can vitamin D be overdosed?
The recommended dose of 400-500 IU per day is absolutely safe. Overdose at this amount is virtually impossible. BUT: don't give multiple drops at once if you forgot. Simply continue normally the next day. If accidental overdose occurs (e.g., baby drank half the bottle) → call poison control.
