Some formulas of simethicone can be suitable for babies, but this doesn’t apply to every simethicone product as it may be mixed with other active ingredients which are not child friendly.
If you think your child needs simethicone to ease their trapped wind, speak to your doctor or pharmacist so they can recommend a product that’s suitable for them.
For example, if your baby has colic, your doctor may recommend Infacol drops to ease their tummy and make them feel more comfortable, which may help to relieve colic but should only be used under medical supervision.
