It's funny how spending priorities change from the first child to the second or, gasp, the third. With my first son, I registered for all the newest, brightest, and most expensive baby items. The nursery was all set, the closet was full of clothes organized by size, and my hospital bag was packed weeks ahead. With my second son I cut some corners: no new baby furniture or gear, and hand-me-down clothes even if they were slightly too large or out of season. With our third child, nothing was ready. I was sure No. 3 would be another boy. Surprise! Our daughter's arrival presented some spending challenges. Here's how we dealt with each one.
