For toddlers (1–2 years old) I recommend caution. Caffeine on the skin can be absorbed and toddlers are more sensitive because of thinner skin and lower body weight. While most safety summaries list low concerns, some scientific reviews and animal studies show effects at higher doses, so we treat this ingredient more carefully for young children.
If possible, avoid products with caffeine for toddlers. If you do use a product that contains caffeine: use it only rarely, apply a very small amount, keep it away from the face, mouth and hands (children often put hands in their mouths), never apply to broken or irritated skin, and rinse off promptly if you see redness, rash or behavior changes. If your child has repeated exposure (daily or on large skin areas), talk with your pediatrician.
Watch for skin irritation, increased fussiness, sleep changes, or unusual behavior after use — these could indicate absorption. The caution comes from several scientific and regulatory reviews (for example IARC, EPA, CIR, ECHA and Environment Canada) that note limited lab evidence of mutation, some animal effects at higher doses, and differing regulatory stances. Also be aware some product certification programs restrict use of caffeine unless manufacturers provide extra safety data.
