Tatum sits. No, not as I plop her down in her Bumbo, but ON HER OWN! At one point, she was on her back playing with sucking her Fisher Price Radio
and the next moment, she was erect! 
Now, I never would “label” her a sitter, but this really helped today at Safeway. I have always wondered when you move from 1st foods to 2nd foods. Thank you Gerber! Now they have a little person in the corner which designates what your baby’s stage should be. Ex: 1st foods: “Supported sitter.” 2nd foods: “Sitter”. (Coincidentally?), today, I bought her “sitter” foods. The difference? Size and mixtures. Child abuse would be if they had pureed spinach in a bottle. (when I was young) Now, they disguise it in “Garden Veggies” which is peas, carrots, water AND a wee bit of spinach. Smart. So, today? We shall try this concoction as she is now a SITTER!
