Quoting Jenna + 2!:" My son has been developing normally until now. His head has always been big but just recently got bigger ... [snip!] ... heard back from our paed but the technician said in his report mild hydrocephalus. How does this just happen all of a sudden?"
i asked the same question about my daughter but i guess it can happen at any time! just be for warned though if he all of a sudden quits communicating and being a verbal and physically active little boy you might want to look into getting him so occupational and speech therapy!
