First time editing photos in RAW format

So I finally decided to try doing a serious photo shoot and attempt to develop my images from RAW format. I decided that getting a perfectly crisp black and white photo is a lot harder than it looks, especially when your subject is a rambunctious toddler. I am quiet pleased with the two that turned out to be in focus. Please let me know what you think!

This is my Baby boy! Benjamin's looking more boy and less baby everyday! He's actually thinned out a lot since he started walking. No wonder, he's everywhere! I wish I had his energy!

In this picture he seems to be a good mix between Kate and Kirk. All of our kids look alike, but none of them have their parents coloring. Kate and Benjamin get their blue eye's from their Grandpa Mower.

I like this shot because of he light reflecting in his eyes. His skin looks a bit pale, I hate the pale vampire look. I'll have to play around on photo shop to see if I can fix it. His hair almost looks red in this photo. Maybe there's some hope that he'll turn into a strawberry blond!

This photo isn't very crisp, but you can't beat the smile! This is one I snapped of Kate. Still not as focused as I'd like, I can't believe how hard it is to keep a steady hand, I think in low light with a higher ISO setting you almost need a tripod or something. Anyways if anyone has some tips to get a more crisp focused portrait let me know. It looks fine when it's mini like this, but It's really out of focus when it's full sized on my computer monitor. I love the expression in this one, She was not very happy about me doing a photo shoot on her. My kids are getting pretty fed up with getting their pictures taken. I think the wedding a couple of weeks ago ruined them. They never want to pose for another picture again.
