I would recommend the Tommee Tippee Digital Ear Thermometer. There is lighted LCD screen so you read the temperature in the middle of the night. Also stores previous readings, so you can better monitor.
Go for the ear thermometer. The infared one's are not accurate. Based on my personal experience
Any particular type of thermometer that you have in mind?
Braun ear themormeter. I've had it for years.
i would recommend braun thermometer!
