I know what you mean! And if you think the urge is bad now, just wait til' that baby shows up!
DH is always telling me stuff like, "Ya know, a person doesn't really need eight diaper bags..." But, I do! I really do!
We put our house on the market when we had three babies in the house... just because we needed a bigger house for all the baby stuff!
But, it's part of the joy of it all. I can't wait until you just get to go spend, spend, spend.
