For the baby photo: I don't really like the angle of this shot. The side of the face makes me loose interest in the photo. Also the coloring seems a bit off I can't exactly say what. Her face almost looks like the texture of stone. Almost as if it was over sharpened. Children photos look best with softer textures. And sharpness in the eyes.
I think the photo of your daughter would be better if you were directly infront of her face. To catch her big beautiful eyes. Otherwise with this angle my focus goes to the redness in her cheeks instead of the eyes.
I notice that also on the black and white photo. The texture of the photo and the blotchy tones of both the hands and feet take away from the tender moment. It looks over exposed in areas and may actually look better in color. I also would have gotten the entire hand in the shot on both sides. cutting them off takes away from completing the photo. Composition otherwise is good with this photo.
I'd tinker with your settings a bit and perhaps do some other post processing.
Keep working with it
