Twinkle is so cute and she is going to be tiny. Izzy was tiny like that and still is. She will be 10 mos next Monday and she is still only 2 pounds 6 ounces. You are right - her little legs look like toothpicks and could easily breaked even if you sat on her by mistake so we are constantly watching where we step, where we sit,etc. I love the bell idea but she doesn't wear her collar in the house but I was just thinking we should have Isabel make some bows with bells attached - that would be cool.
