btw if sleeping bag does trick go Baby factory and buy some footed PJS - HUGE range just out (Leish left some at botany store) and try those...then it doesnt matter if no blanket etc...
we had some from USA last year and got more sent over this year...worked a treat - ella was always warm but not restricted (which can be case of sleeping bags) - I LOVE footed warm pjs - they make adult sizes too but im too chicken to wear them!
