Hi sarah,
I havent been on here in ages so only seeing your post now. My daughter Orlaith was born with hydro and had her vp shunt inserted at 3 weeks. So any questions you may have from a different view (ie. from one mum of a child with hydro to another) please ask. may even have some for you at some time in the future.
i do worry about orlaith but she is such a happy baby, she is doing great and all her hair grew back within a couple of months. She has now grown into her head so to speak, she is 17 months now and has just started crawling (she also has low muscle tone) so is having a ball exploring the house on her own terms
