coming close to week 3 with Claire

she'll be 3 weeks old this coming Tuesday. Last night she slept a little better than the night before. She still hates to sleep alone. I wonder when that will end. One of us constantly has to be there while she is sleeping in order to be content. I am told it will get better but I just wonder when and how. If I can't put her down for a nap without her whining, I don't know how it will get any better. I guess thats just my ignorance as her mommy. I hope anyway
