Babies, particularly in the first year, are often measured in terms of milestones. For first-time mom Keri Russell, one recent milestone has made all the difference — the smiles being given by son River, 5-months.

Keri says that she was surprised not only by how tough the sleep deprivation of raising a baby has been, but also her emotional response to children everywhere.

Keri, 31, has been married to Shane Deary since February.
