Feather weight?! ahhhh...NO!

We put R's unused cot in the hall, as we thought it might be conducive for me to put her in the cot, when I need to do some chores in the kitchen. Hubby was sleeping next to the cot today, while R was playing. We were not sure what she wanted to do. R just crawled to hubby's side, started clamouring over his body, and suddenly, she was standing on his belly/chest, holding the side of the cot! She must think that she's light!!!!!
R does this stepping on us quite often, especially in the morning, when we let her play on our bed, while we try to register how early it is to be awake! She seems to have no problem climbing over us, stepping on our tummies and kicking our sides to push herself up!
