DD is 3weeks and clearly does not enjoy being swaddled, mainly I think because she struggles with farts and poos and spends a fair amount of time straining and stretching in her sleep. We tightly swaddled DS from birth til about 6months so I don't really know what to do if I don't swaddle DD - do I wrap a blanket round her under arms? How do I make sure she won't pull blankets up over her head? She's still a bit little for the grobag I think, and I worry her shoulder and hands will get cold...
