Maybe when DD was around 1 and I could not hold her down by myself without straddling her ! I use a ditgal thermometer under her armpit(adding a degree). And now that she is 5 I can use the ditgal in her mouth.

With DD1, we kept using the rectal until she got tubes and the ear infections stopped - about 14 months. With DD2, we stopped at about 12 months when our rectal thermometer died. Now we use an ear thermometer.
