I think Lucy has the strongest tummy muscles of any of my babies at this point. She is just one bound and determined little girl to go somewhere fast. Today I REALLY needed to go to the bathroom but Lucy was being kind of needy. So, I buckled her in her bouncy seat in my bathroom so she would be nearby. I was only in the restroom for about a minute and came out to Lucy completely sitting up in her bouncer. Alex was sitting on the floor next to her just laughing. I guess we will not be using the bouncy seat anymore.
