At the moment my dd sleeps wrapped in a large bamboo muslin (not really properly swaddled, just enough to stop her startling herself or rubbing her face in her sleep) with a cellular blanket on top, but she sometimes wakes up now the weather is cold because she kicks the blanket off. I've got a 2.5 tog gro bag but as she is used to being wrapped in the muslin I'm concerned she will flail her arms about and wake herself up! Is it ok to wrap the muslin around her outside the grobag or is this a total no no? Would like her in a gro bag before it gets really cold but unsure how to transition because she sleeps so well. Any ideas?
