I once had a B-D thermometer that looked just like the yellow B-D rectal thermometer shown. It came in the same blue case and was yellow. Anyone else remember this kind?

Come to think of it, the difference with mine was that it was labeled as “Baby” rather than as “Rectal.” Hard to think there was any difference between the two and I wonder why the distinction even existed. But I think I remember seeing both “Baby” and “Rectal” thermometers hanging separately on the rack in the drugstore in the 80s or 90s. Does anyone else remember that or know why?

I wouldn’t swear to it but I believe the stubby/safety/baby thermometer bulb was intended for young children For safe insertion.

I have BD yellow back from the 1970s.

I would imagine that the word baby/rectal were terms used for marketing. The only difference, was that the rectal had a larger bulb. Maybe the idea was that it would be preferred for use by all ages.

Great whackin material, thanks for posting!
