I rarely bathe my kids. It might be laziness or a pseudo-hippie affection for funk (my own showering schedule is a little suspect!), but that window between dinner and bedtime is always such a chore that a bath is the last thing on my list. Instead, I fill that hour by getting outside. In the past we've loved walks around the block, collecting rocks and leaves, but now that we have a newly fenced tiny little yard of our very own, I can simply turn them loose. What a revelation! It may not be the fields and streams and forests of my own childhood adventures, but a hose bib and a few square feet of turf is plenty to save all our sanity at the end of a long day.
P.S. I know it's crazy how big these kids are. Where did my babies go?!
