Our first couple and a few other low-key days consisted of bakery visits, going on walks, playing at parks, and simply soaking in the fresh outdoors. My SIL and her family live in a conveniently located, quaint, little town so it was ideal for being able to enjoy the countryside, yet close enough to all sorts of other entertainment and activities.
During the trip, I made a conscious effort, and had the chance to really watch the kids. On many occasions, I was overwhelmed with the realization they're NOT babies anymore (I know, duh!) - I think I have a condition that makes it hard for me to let go of their baby-selves. :p
Maybe it was seeing them in such unique and special-opportunity places and situations, or the impending 4th birthday and start of an official pre-K that's got me all emotional.. Either way, gratitude, amazement, and even teary-eyes brought me down from the common chaos of the day-to-day activities, and really helped me to continue working on 'letting go' and giving these little 'kids' more and more independence.
