Need..... Sleep...... Now.....

As I write this Lily is softly "Crying it out"........... Here she is eleven months old and still waking up about twice a night. I am so tired and I just want her to sleep a whole night. It would be amazing if she would close her precious little eyes and keep them shut for atleast eight to ten hours. I feel horrible that she is crying and I feel like she is probably in there so confused at why I will not come get her. Advice? I read all these sites from women who "co-sleep" and would Never Ever let their child Cry. Oh my goodness. If that is what you choose to do with your children, then that is great but I really love some alone time with B and I really am selfish about my sleep. Needless to say, it is time for Lily to learn to self soothe. Right??? so why am I feeling so much guilt about it? I'll give her a few more minutes and then I'll probably cave :) xoxo
