I would normally classify myself as sedentary but as of today I will be watching my 2 great nephews ages 6 weeks and 2 years old. I think I may need to change my lifestyle to lightly active but am not sure. I will still be able to be sitting much of the time but I'll also be wrangling an active toddler and carrying a baby part of the time. I'll be fixing meals and bottles for them and changing diapers too. Is that enough activity to justify changing to lightly active from sedentary?
