Definitely a sling. At this age we had no routine (well, kinda early for one I guess..) so that was good in that I could take bubs anywhere. We did use the sling ALOT during this time also, particularly as none of my three slept well. If you do havea good sleeper, you will get away with pram, portacot etc if you go out. I think if you have these three things on hand it should be fine xo
