Any suggestions for what to get? Am expecting DC2 in a few weeks and will be getting the 'big' pushchair back out again. DS (2.9) currently gets shoved in a stroller if we're going to be out for a while - he is getting better at walking places but he dawdles a lot so I would like an option that might hurry things along a bit. Am prepared to try baby in a sling for a while and him in the stroller but want a back up for longer trips...
