Yay baby sleep!

So for the past two nights Colie has gone to sleep in her bed on her own. Last night was easy as pie. Tonight she cried lightly for 10 mins then it changed to worse so i went in and put her nuk back in covered her up and haven't heard a peep for 15 mins now. Aiden was such a difficult sleeper. He wouldn't sleep anywhere but with us. And (this is bad....) he would only fall asleep in someone's arms. Then we moved into this house and he started sleepin alone. And then he started climbing out of his crib so we took down the side and he wouldn't sleep anywhere but the couch until about the time we found out that we were pregnant and needed his crib/toddler bed for the new baby. He got a new bed with a pull out bed underneath and BAM slept in it alone on the first night. That little creep let me tell you.
