My LO has a bunch of smiles! My favorite one is when she wrinkles her nose, her eyes get smaller and she grins from ear to ear! She usually flashes this smile when we pick her up from daycare and after a big meal!
Her fake smile cracks me up...she usually grits her teeth and gives a pained smile when she is nervous! She flashes this smile a lot when we FaceTime with my parents....I think she is scared of all the weird noises they like to make when they talk to her!
Does you LO have different smiles?
