You are full of great ideas! I looked at your shop and those toddler belts are great! I have to put 2T jeans on DD to get the over the fluffy but and provide for her long legs, but the waist is always huge! (She's 9 months, 30 inches long, and 19 lbs -- my little amazon)
I'm no help on the bib/shirt ideas. I do think a bib is better than a shirt, though.
