To be honest, I think if it was just me, I'd use a baby wrap/sling/carrier before moving. I say this because for both boys I had a pram, and pretty much never used it in the first few weeks. If you hire/have a baby car capsule in the first few weeks, you can always bring that inside if bub needs a portable bed. But for walking, shopping, etc, I'd go the carrier.

Alternately, do you know anyone here who'd be in a position to lend you their pram for 6 weeks before you leave?
