This particular back-to-school was a milestone for our family. Our son, now a preschool graduate, started Kindergarten this year. This transition from daycare to Kindergarten brought up all sorts of feelings. Excitement and worry topping the list.

On the first day of school, my son boarded his bus with such enthusiasm that he didn't even look back to wave. I smiled because I knew my child was ready. He had nearly a week of 'practice' Kindergarten at his new school and loads of practice at his preschool, too. He'd met new friends and was excited about his expanded schedule. What surprised me on this first day of school - along with the fact that I didn't shed a tear - was that after the bus drove away, I found myself facing a void. Now what?

A few minutes later, I met four moms whose children had shared a similar new morning routine. As we sipped our coffee at Starbucks and shared the freshness of the first day, it hit me: I wouldn't be seeing these moms every day anymore. These women weren't just the moms of my son's preschool friends, these gals are my closest friends. We'd seen each other nearly every day for past five years at drop offs and pick ups. Sure we'd all be saving nearly a thousand dollars a month (yay!) now that daycare was done, but this aspect of my son's transition to Kindergarten I didn't see coming. I'd been so caught up in his 'what ifs', that I didn't realize until that moment that my friendships would be changing right along with his. MY FRIENDSHIPS. We'd still see each other at birthday parties, swim lessons and occasional play dates, but would we still share those day-to-day mom moments and meltdowns? Not likely.

On the eve of my son's school's new parent orientation, I find myself wondering...will I make any new friends tomorrow evening?

The bond between daycare kids and their friends is a strong one. They're noticeably close, even though they now go to different schools or attend different classes. I suspect that although our daily routine is changing, the daycare-moms-turned-Kindergarten-moms will stay pretty tight, too.

Meet "Piggy". Piggy is part of our family and is helping us teach our young son the importance of giving back.

Piggy was a gift from my friend Kelly at my baby shower. Eight months pregnant at the time, I felt a lot like Piggy. But alas, Piggy was a gift for my son. He's been in our boy's bedroom since before he was born and does his best to blend in with with changes to decor over time.

He's currently half full with silver coins with a few paper dollars mixed in. Our son is saving for gifts that he will donate at Christmas time to the "kids who don't have toys to play with". He's very serious when he talks about Piggy and knows exactly what Piggy stands. Everything inside Piggy is his to give back.

We also teach our son about giving, by doing just that. He's helped me donate clothing items, baked goods, gently used baby gear, books and just about everything else we aren't currently putting to good use. We also talk about the beauty in receiving. For back-to-school, we bought a pair of TOMS shoes together online. I showed him what the purchase of my son's corduroy lace-up shoes means to a boy in Haiti or Cambodia or South Africa. A pair of shoes. "You mean he doesn't have any shoes, mom?", he asked. It's a fact of life I feel compelled to teach our young child. We are very fortunate. Others are less so.

Today he asked to shake Piggy when we added the money he earned at our recent garage sale. "There's a lot of money in there, mom".
