Hi intellisyte!
Yes, it happens to me as well. I am no longer weirded out by it though!
Babies still have a large connection to the other side, which includes being able to see the energy fields (or auras) around us. They recognize energy workers (whether the energy workers realizes they do that or not) and they are happy to see a kindred spirit.
Kind of like being in a foreign country and running into (for example) another American - a kindred spirit. An "ah! I am not alone here" feeling.
I usually make eye contact, smile (a no teeth smile) and (mentally) talk to them. That usually brings a bigger smile from them.
Does that help?
