Ellie learned to laugh.
Which is good, because baby giggles are nice. But first she was surprised. Because that’s the way she is, and you would be surprised too if your mother started blowing raspberries on your tum with no warning.
Also, I know you can’t hear the laugh, because it’s a picture, but if you’ll just give a very adorable gurgle while you grin widely, that’ll be a reasonable facsimile.
