Will baby cry if rectal thermometer went in too far?

If a rectal thermometer is inserted too far, it can cause discomfort or pain, which may lead to the baby crying. However, if used properly and as directed, rectal thermometers are safe and should not typically cause distress. It's important to follow the manufacturer's instructions and only insert the thermometer a short distance (usually about 1 inch) to avoid any issues. If there are concerns about proper use or if a baby seems to be in pain, it’s best to consult a healthcare professional.
