#1 is great, and I love his expression. Kids are so much fun.
#2 is very pretty, and I like how you used the greenery to frame her.
#3? If she's anything like my wife, she'll hate her arm in that photo. I usually snap 4-5 of these shots in a row so I have a few to pick from, usually opting for the image with mom's arms fully extended.
#4 is a very nice B&W, and the lighting is soft and pretty. But her eyes don't need to be closed. I've have her just looking down at her belly instead. That's just me.
