The second part is us getting over the superstition element: buying the kit means accepting that things are now OK, that Toblet(te) will be born healthy, wealthy and wise. Put another way, stop worrying and start planning. (According to top bloke Norm, proud possessor of two teenagers, the worrying *starts* now and continues to build for the rest of your life...)
It's a strange transition: single - couple - expecting - dad. Accepting Yes, this is happening, is the biggest change. Bye-bye superstition, Hello reality.
