what's the innocent form of stalker?

Noah has a favorite baby: baby Iona. He perks up anytime her name is mentioned and begins repeating "Ona," "Ona," "Ona." If we mention Iona's parents by name, Noah ensures we remember to include "Ona" too.

During brunch one day, after Iona had gone down for a nap, Noah was content just watching the baby monitor as his little girlfriend slept.
