Hi Amy,
Welcome to NeuroTalk. I'm so sorry that little Warren has had such a complicated month...I've posted the link to the Children's Forum for you. Possibly someone there has been through this experience. Please let us know if you have any questions. I'll keep you and Warren and your whole family in my prayers. Please keep us updated as to how he's doing. We all care.
