How do I get my 1 year old to sit still while trying to take her temperature with a rectal thermometer? She’ll sit still but as soon as it hits normal body temp and going to rise she starts to kick and lift her butt up. I am afraid she is going to hurt herself. Should I turn her onto her stomach? I’ve purchased a ear/forehead thermometer but it seems to be off almost 2-3 degrees!! For example, I took her temp via forehead and it said 97.2 then took it rectally right after and it got up to 99 before she started to kick!
