Linny, I'm not even ready for another yet...my dd is just 13 months & I do some of the things you mentioned....I am always checking adoption sites & following leads on adoptable children -- so at least you're doing it for the ultimate result of having another child
& not just a loon like I sometimes feel like
I truly don't feel like there is a level of research that is 'too much' unless it is leaving you feeling in a negative way....I equate to a bio mom's pregnancy time & as mom's we feel like we have to be actively doing something towards having our child - just my thoughts.....good luck & I hope you bring home another dd soon!!
