Some parents are happy to leave their children to their own devices on holiday, but not Sylvie van der Vaart. The model mother-of-one was up and about with her son Damien on the beach, playing games on the sandy shores of Miami. Wearing a floral bikini, Sylvie, 35, definitely proved herself to be an active, hands-on parent. Clearly Sylvie knows that switching up the style and shape of her bikini on a daily basis will leave with the least amount of tan lines; evident by her enviable bronzed skin.
