I’d say she started a few days ago–so just about 5 weeks old. They definitely aren’t just gassy smiles, they’re real! Steve is better at getting her to smile than I am, but if you make some clicking noises with your mouth, it seems to do the trick. Sorry for the crappy iPhone photos, but I wanted to capture the smiles and it’s all that was nearby. She is just starting to make coo-ing sounds too! <3 Love!
