We started doing baby sign language with Opal early—just a few signs—and sometime during her ninth month she started consistently using the sign for milk. She does it for nursing, drinking water, and eating so it’s not perfect but gets the point across! We can usually tell when she’s hungry, but there have been a few times she’s surprised us by asking for milk and really wanting it. She also asks for milk when she’s tired and ready for bed, too. It’s super cute. We’re still working on the signs for more and all done—hopefully those are next!
