Mohamed and Ahmed Ibrahim celebrated their fifth birthday on Friday, the Dallas Morning News reported. They have been back in Egypt since November, after going through two years of physical therapy.
The boys, who were joined at the crowns of their heads, still wear helmets because their heads have not completely healed from the surgery. Dr. Mamdouh Aboul-Hassan, who arranged for the surgery in Dallas and now supervises their care, expects the helmets to come off this year.
He said Mohamed's right hand is still weak, and Ahmed uses a walker because his limbs are still not strong enough to support him.
"I don't believe I have them in my home and they are doing so well," their father, Ibrahim Mohamed Ibrahim, said, speaking through a translator.
Their mother said the boys still think of Dallas as home and think they are in Egypt on a visit.
