Evidently, Kali 0.6 is a substantial version upgrade from the 0.5 version Mrs. Lime and I had only a week ago. Here's a few good examples......
If she needs something really badly, she'll let loose with a good, hard cry (usually involves food or sleepy). However, she's now perfecting the 'attention whine'. You parents may know what I'm talking about. If she feels like she's being attention-starved (which is usually ever few minutes), she'll let out a smaller, but consistent whimpering cry to get your attention. When you turn your head to look at her, the frown on her face quickly reverses to a smile as she realized that she now has your undivided attention. It's becoming a game at this point.
Rejection of spoon-fed food has reached a new level. Before, she would just turn her head away. Now, she's gone to more aggressive tactics. If you stick a spoon of food to her mouth when she's full or doesn't like the food, she'll pucker her lips and blow/spit that food right off the spoon. We've worked around her rejections initially by getting her to smile, which opens up her mouth for a quick spoonful. She's now become wise to that move. We'll try to get her to smile now, but she's perfected the closed-mouth smile which allows for acknowledgement of the funnies while avoiding a spoonful of food. She's also getting good at grabbing the food bowl/container and flipping it over if you don't pay attention.
Kali's leg strength has been increasing with her play-time in the Exersaucer. As a result, her legs are very strong now. I set her up against the coffee table yesterday. She was able to stand up with her arms on the table without any help. I kept my hands nearby to catch her, but she did most of the work and stood for 15-20 seconds on her own until she tried to make a step and fell back. She's also making crawling motions when on her stomach, but her arm strength is behind her legs a bit. I have no doubt that will change in the near future.
She's also acting adversely to dirty diapers. If she's got something stinky in her diapers, she usually starts fussing. She's quickly figured out that she does not like wearing dirty diapers for very long. Switch the diaper out, and Kali is happy again.
