Ah, parenting. For 100 different issues there are at least 200 ways to address them and generally, my feeling is do whatever works for you, your child, and your family. But every once in a while I do have to chuckle at how different we can all be in the way that we approach parenting.
Like when O was 18 months old, I was in a conversation with two women where one was lamenting the fact that she couldn't find a dance class that accepted children under a year and a half. The other women readily agreed and replied "I know! Because by the time they're 18 months old, they're already involved in so many other activities!" At this point I nearly spit my coffee out - mostly because their child's life and my child's life could not have been more different.
Up until this point, we've done one session of swim classes with O (in which I complained about how cold the water was) but other than that we've been "super-lazy parents". And while we fully embrace that moniker we did recently sign O up for her second ever activity - a little gymnastics class which pretty much consists of her running around, jumping on a trampoline and throwing herself into a foam pit. And I have to say, it's adorable and highly entertaining to watch. I can almost guarantee that we'll never be the parents of a toddler with a jam-packed social calendar, but an activity like this every once in a while sure is fun.
