I have B/G twins who are 11 years old now. When they were near two years old they enjoyed Megablocks and the Fisher Price Little People toys (barn, school, school bus, etc.) They were toys that were appropriate for both boys and girls and they played well with them together. Of course we got cars for our son and dolls for our daughter as well so they had something of their own for Christmas. Have fun. They grow up quickly.
