Hollywood star Brad Pitt is the latest celebrity to catch the attention of child care experts after he was photographed cycling with his adopted baby daughter ZAHARA strapped to his back. The Troy heart-throb is currently in Namibia with his pregnant girlfriend Angelina Jolie and their adopted children MADDOX, 4, and Zahara, 16 months, awaiting the birth of their first biological child anytime now. Photos taken last week (18MAY06) appear to show Pitt cycling in the village of Langstrand with the young tot riding on his back in a papoose. Child expert DEBRA SMILEY HOLTZMAN, author of THE SAFE BABY, says, "Zahara needs a helmet and closed-toe shoes. And I highly recommend toddlers ride in a child trailer pulled by a bike. It's more stable and secure." Baby Talk magazine editor CHRISTINA VERCELLETTO adds, "(Makers of the papoose) specifically say, 'Do not use while riding a bike.' It will affect your balance. The safest place for her would be in a toddler bike seat."
