First, if you have one DYS, you should have three sets of usernames/passwords. As I have two DYS, I have four sets of usernames/passwords. Make sure you are using the appropriate ones because the usernames determine which parts of the website you can access. Each child has his/her own username/password to access/post on the kid sections of DYS and other then keeping a record of these, you obviously shouldn't be using them. The parents have one username/password to access/post on parent sections of DYS. However, before either you or your child(ren) can use your individual usernames/passwords, you have to log on using the shared username/password to access the website.
