OK so I have a question, I'm a mother of three and my oldest two never had a problem sleeping in their cribs at night. My 4 month old daughter refuses to sleep good without being swaddled (my other two hated being swaddled since they were about 1 week old) it just makes me nervous because she moves around in her crib at night and sometimes gets free. I'm just scared she's going to end up covering her face with her blanket and smothering herself, any other mother have any advice?
