Has anyone got any useful advice on unwrapping bubs to sleep? My baby boy is almost 5 months old and will not sleep unless he is wrapped. He is not rolling over yet but I know it will happen soon and hear it is unsafe to keep them wrapped when they can roll. At the moment, if his arms are out he waves them around like crazy until he gets so worked up he cries and gets upset. Any ideas on how to start unwrapping?
