Are forehead (infrared) thermometers reliable for babies?

Mixed. Specialist parenting subreddits frequently call forehead thermometers 'notoriously inaccurate,' while testing-focused sources like techgearlab.com rate the better infrared models highly. The realistic take from the data: forehead/no-touch units are fine for quick screening on wiggly toddlers, but reviewers consistently warn against trusting them alone for a young infant.
