I got my first four girls today, and I am all ready in love with them. Three of them are all ready eating and drinking and talking and looking around since we got back from the store, but one is just laying down and only moves when one of her sisters (I don't know that they are biological sisters, but they are here) walks on her. She's right under the lamp where she'll be warmest. Is this all I can do for her? is there any way for me to make her feel better?
