Check price on Amazon →As a parent of two and a former pediatric nurse, I have tested every type of baby thermometer. These are the ones that give fast accurate readings on squirmy kids.
I worked pediatric nursing for six years before becoming a parent myself, and I have used every category of baby thermometer in clinical and home settings. With a wiggly toddler at 2 am, accuracy and speed matter more than features. Here are the thermometers I actually keep in my house.

Common questions
Rectal. The AAP still recommends rectal temperature as the gold standard for infants under three months because forehead and ear readings have higher error margins at low body weight.
100.4 F or 38 C taken rectally. For infants under three months, any fever should prompt an immediate call to your pediatrician or a visit to the emergency department.
