What do you mean by pop in to the movies?? i haven't been to the movies in 2 years because i couldn't take a baby/toddler to the movies and i wouldn't take a toddler and a baby to the movies.

As for the sling i'll be using a hug-a-bub which keeps the baby so close to the chest i can bend down, do the house cleaning etc and in most cases they are happy to sleep in there. My DS wouldn't ever sleep unless i was carrying him... not even in the pram.

I really don't want to invest in another single pram or a double pram, i guess i'm hoping i can get away with carrying the little one and using the stroller for DS.
