Cute family. Great job on these. Here is my CC, JMO:
The first picture, looks like the boy is a bit soft or OOF. He was probably moving? Also, it looks a bit on the cool side to me.
The second one is nicely done. A bit too centered for my taste. The sun or light seems to be coming from the left (our right) - you should have had them facing that way to avoid any uneven lighting, or use a reflector or a speedlight.
