I don't see anything wrong with trying a leash on the baby! If it's for safety and things like that then great! If it's all the time, I think that's kind of messed up (my godson was on a leash for DisneyLand - didn't want him running off and getting hurt)
I had 3 months of TTC, so it wasn't first shot, but was really exciting when I did get my BFP.
Right now I'm already tired of seeing BFNs (I've been testing on Fridays since I don't have an AF to know if I am or not). Jess - crazy that it took so long for your test to show up positive!
