I thought that's what you were using. I hope to write a book some day so I'm comparing photo' of Grey's at different ages. Babies from different back grounds look some what different from each other, and when age is given in weeks, that can be off by as much as 3 days either way! I'm very sorry, no offense was meant to you, nor was I doubting your word!!! As far as the temp is concerned, that was also just a question I asked, some people keep it on the high side of 90, others on the low side...At my rescue we keep it at the high side. Sorry again, I have no doubts about the great care and devotion you'll give this wonderful creation!!!!! Sorry Jayd
