The one that can sposor your son is his father otherwise he will not be able to come to qatar. I do not think they allow mothers to sposor their own children.
My son goes to Little Angles. We are so happy with the nursery. The staff are very friendly and honest. They have a nurse too. My son learned so much at Little Angels in comparison to the other nursery he was attending. The director, she is fine. Very friendly especialy to the children.

Good luck with your job offer.
