Supergirl: when she raises her arms above her head. Also, since her neck is stronger, when M holds her she looks like she’s flying!
Stevie: Because she loves to bob her head around and look at everything.
Stretchy Monster: When waking or after eating, she’s the queen (and monster) of stretch! Her back arches, her face stretches, her cute chubby bum sticks out. When she was inside me I could feel her stretching all the time, and it’s so wonderful to see that on the outside, and know that I was learning about her before she was born.
