thermometer for newborn?

Clarissa • Mama
What brand and type should I get??
I won a Withings no touch forehead reader, but I think I want something different for the age she is now. It's great for my husband and me, but my baby is 2 months and I don't think it's accurate on her.
I have nowhere to even begin.
Digital or analog?
Rectal, ear, forehead, mouth?
Help!
