How was your rectal temperature timed?

When I did the temperatures I always just waited for the thermometer To beep

Wristwatch at home or pediatrician office. I remember as I got older holding the watch counting the times it went around.

Normally the thermometer did it by itself. If it beeped it was ready. In rare cases where mum had to use the glass thermometer, because of dead batteries or because of mum letting the digital one drop once too often, I guess she used her wrist watch.

@Mini_Jenni Until how old did she do it rectally?

@Pecan_nutjob last time she did it was 15. After that I did it by myself.

My mom used an hourglass egg timer

In Finland, the measurement always took 15 minutes from the armpit and 10 minutes from the rectum, oral measurement is very rare in Finland. usually mom looked at the time on the bedside clock

Mom's watch or gut feeling. Maybe longer while she waited on hold for a nurse / office to answer.

As far as I remember, both my mum and my pediatrician, used their wrist watch for timing the measurement.
