My little mummy

Kelsi has never really needed to be swaddled. I always did it when she was a little teeny tiny thing, but never very tight, and she would always get her arms out and sleep really well. She goes to sleep with her "binky" and of course it falls out of her mouth once she goes to sleep. It is a MUST to go to sleep. So, my dilema is this: For the last month or two, Kelsi takes the binky out of her mouth and plays with it, turns it around and bites on it, uses it as a teether and throws it (you would think she could drop-kick it with how far we find it from her). In order for her to go to sleep (naps and bedtime), I have found the only thing I can do is swaddle her arms down so she can't pull it out. It works like a dream. What is my problem, then? Well, it's 100 degrees outside, so I have to make sure it is pretty cool in my house so that I can wrap her, she is growing so big that I currently only have about 2 blankets that even work as a swaddle blanket . I know that in a few months she can just crawl and get her binky in her crib or at least figure out how to put it back in her own mouth correctly and this won't be so a big problem. Anyway, I am open to suggestions, even though I don't think there are any other alternatives (don't think that I haven't thought of taping it to her mouth - I wouldn't ever do it though). If I don't pin her arms down, she will never fall asleep since she will pull out her binky. (sigh). And what am I going to do whenever I go down to LA to visit my parents who don't have air conditioning? I can't wrap the poor kid then!!! HA! I was just thinking that I am glad that this is the biggest of my problems with little Kelsi. She is such a good girl. JUST LOOK AT HER IN THAT PICTURE. AWWWW.
