A newborn smiles...Someone, somewhere must utter the obligatory phrase: "It must be gas." I've got such a bone to pick about this old saying!
First, I've worked with hundreds and hundreds of babies. I've never seen one baby with gas smile. Have you?
Second, when a newborn screams or cries, who doubts the authenticity of that emotion? Most people trust that a baby is legitimately unhappy....So, why can't that same baby be genuinely happy?
I think the basis of this old myth is that a newborn baby just isn't developmentally capable of a full range of human emotion. I disagree.
There is a different quality to the 'Social Smile' that usually emerges around 6 weeks. This smile is more purposeful and used for interaction. Smiles seen in the first weeks seem to be more internal and not seeking a response.
While I'm waiting for Developmental Psychologists to back me up on this, I'll stand firm in my opinion that babies are whole people.
