Yes, the NHS recommends that all breastfed babies should take a vitamin D supplement every day from the day they’re born.
Formula-fed babies may need to take these too, but some formulas are already fortified with vitamin D, so make sure to consult with your healthcare team about this if your baby is taking formula.
After six months old, your baby should start taking supplements of vitamins A, C, and D, this will continue until they turn five.
Again, remember to consult your healthcare team if your baby is formula-fed.
