She dosen't even look sleepy!

Tonight as I was going to put Evelyn to bed J said she didn't look sleepy and that we were going to be in for a rough night. brushed her teeth and read her book and put her in the crib with a nuk. she took the nuk and went to sleep with in 10 minutes with little crying. I think she has been over tired when we put her to bed however we do it at the same time every night. She has trouble with nap times so I think that contributes. I just wish she went to bed like this every night. We will keep trying...
