Okay, if you manage to find the board your looking for, look on the top right-hand portion of the page. You will see "Join this Exchange". When you click that, the board will show up in your "My exchange" section on the left-hand side.
This should make things a little easier for those who havn't found it yet.
Also, if you go to the homepage of the exchanges, go to P and scroll down to parenting. The origonal posts are under Parenting: X to Y months or Parenting: Z years.View Thread
