We are texting all the time - while eating, working, taking a bath and even driving. We do it quickly as possible in order to make a feeling of a real talk. And if there is a lot to say we use emojis to cut up time of typing. One simple emoji can tell a whole story.
So I thought what if babies which haven't yet learned to talk could've contact with their moms with emojis of their own. 
There is a set of six emojis I designed in order to help babies convey their needs and complaints to their moms.
