Last night my husband and I and our 5 oldest kids were playing Apples to Apples,so I put Ruby in her baby bed to watch her mobile.Well,she just cooed and blew raspberries and was quite happy for a long while.Then she started her grumbling sounds,you know not really crying just griping,I decided to just let her be because she wasn't screaming or upset.By the time we finished our game she was sound asleep!The first time she has gone to sleep at night without me holding her!Also the first time she has slept in her crib and not in her cradle by my bed!
