What age can they start?
It varies by product - some are formulated from birth, others from one, three or seven years. The pack states its intended range, and that is the figure to follow.
Can I put a supplement in a warm drink?
Not if it contains live cultures - heat kills them. Use cool or lukewarm food and drink. Yoghurt, cooled milk or water all work fine.
Is the skincare fragrance free?
Several lines are, and it is marked on the pack. Where products are scented it is with essential oils rather than synthetic fragrance, and the full list is always on the label.
Do children need a multivitamin?
Most children eating a varied diet do not, though UK advice suggests a vitamin D supplement for young children. Your health visitor or GP can tell you what applies to your child specifically.
