Yep, Trillian is right! I am losing heaps of hair atm (DS is nearly 6 months old) and I lost loads of hair a few months after my first DS was born too. It will slow down eventually, but it is different for everyone.

Time to stop feeling guilty about not earning money! You are doing the most important job in the world at the moment by looking after your DD. They are only babies for such a short time so just enjoy her. There is time to think about going back to work later. It must be hard having your DH work such long hours, do you have any family or friends who can help you out every so often?
