As the days grow shorter, the weather colder (for most anyway) and we turn our sights to indoor activities for the holidays, many of us inevitably start thinking more about comfort foods.

This is the right time of year for festive feasting, but that doesn’t always have to mean heavy, unhealthy meals.

Is there anything more endearing than the photographs of your baby eating his or her first foods? Their faces squish-up, they are covered from head to toe, their tongues protrude to catch every bite or more often to try to get the revolting taste out of their mouths.
