DON’T SUPPORT THE HEAD AND NECK AFTER 6 MONTHS
Dr. Swanson estimates this baby is around six or seven months old. (Well, in the photo; in reality, she’s almost certainly long dead!) At that age, babies can sit up on their own and don’t require any additional head or neck support. This, as President Warren G. Harding knew, meant she was strong enough to work 14-hour days in a mill.
