Hi Vanessa
Well, I think you have some beautiful pictures there. Is your husband a photographer? If not, he's far less likely to pick up on white balance, critical focus and the like. That's not to say you can ignore them, but if their purpose is making him happy then, well... you can probably ignore them!
Also worth bearing in mind how they'll be printed - take them to a supermarket printlab and they could well mess up any careful white balance tinkering with a poorly set up printer
Funnily enough, I locked onto the same picture as
@CraigDHD - the expression in 76 is lovely. I have a "girly girl" of a similar age (she refuses to wear anything except flowery dresses) and they really do make the most wonderful models.
One trick I use is to try to get something white or grey (neutral) in shot somewhere. A lot of my daughter's clothes have splashes of white in them somewhere. That makes a handy (but not perfect) white balance reference point. You're supposed to use mid grey, but with fast moving kids and scenes which will come and go and need to be grabbed when they're there, getting the grey card out isn't always an option.
Most importantly of all, keep taking the photos as it's the only way to get better. And you're making a great start so far
