K.E.
My 2 year old walked like that. Her birthmother was on drugs during the pregnancy and she was born very very stiff. She received "occupational therapy" to help her with gross motor skills from about 7 months old. She responded very well and was walking at 10 months old but continued to walk very wide and bowlegged until she was about 14 months old. Consult your pediatrician and see if they think occupational therapy could help. It's free in Pennsylvania.
