How much is too much?

I went to a meeting tonight for about an hour. John stayed with Gabby. She cried and cried because I was gone. I know I spend too much time with her but it is so hard to be away from her! John would love to spend more time with her but I don't give him a chance. When I returned home tonight she was so clingy! She kept falling asleep in my arms but woke up and cried every time I tried to put her in the crib. So now, after about two hours of that, John is finished his assignment for his Masters and is taking a turn and rocking her to sleep again. I know what she is waiting for. She wants to go to bed with me! She hasn't slept in her crib for quite some time now. I think that after the holidays I will try to day ween her and feed her expressed milk plus try to get away for short periods of time so that she is not so dependent on me. I have to go back to work in April and I don't think she will be ready for it unless I start making some changes. I never meant for her to be so clingy but I am just not willing to let her cry it out. Look at that face, could you listen to her cry? I thought not!
