those bags are great. no amount of kicking can get rid of them, as with blankets. I just put ds in a sleepsuit and then in the bag. don't need anything else, as ggglimpopo says, she'll overheat. Mine was arms all over the place, but got used to it quite quickly xxx
I must be the only one, my dd is in sleeping bag and i also put on a holey blanket for her to hold and tucks her in, She doesn't get to hot and the times i have left it of she waves her arms around and doesn't settle. HTH
My son had a sleeping bag from about 4 months and that was how he started having his complete nights sleep (and me too!!!) He stopped using it last spring and has not needed one since as he has now realised that its silly to keep kicking his covers off and that I won't keep tucking him in time after time!!! Hes nearly 2 now.
