Hmmm....triggers. Well, for me:
1)hearing someone is pregnant with a baby boy ( especially if they already have a girl)
2) seeing a family with a girl ( oldest) and a boy (youngest)
3) seeing baby boy clothing at a store
4) walking into Babies R Us and seeing someone register for boy stuff
5) sometimes reading a baby magazine and seeing a picture of a mom with her baby boy
6) seeing a mother with her son, or a father with his son
Mom to a beautiful baby 2011 and hoping for a baby one day to complete our family!
