DD is 8 weeks and tends to be a fairly calm and contented baby but becomes inconsolable when we go out in the pram. I currently try to head out when she is asleep and none the wiser although this isn't always practical and I feel terrible, not to mention horribly self-conscious, pushing a screaming infant to an appointment or an activity where we need to be there at a specific time. I've tried talking to her to reassure her, hanging a cellular blanket over the front and bringing Ewan the Dream Sheep with us, to no avail. I long to get to a point where she is awake and happy in the pram - not least so we can go to the shops and set about spending all the gift cards we were sent when she was born! 
Any tips? Is trying a sling my only hope?! I have been looking for a musical toy that plays nursery rhymes with no luck. Does such a thing exist and if so, would that be worth a try?
