Flights, baggage, limits

We're booking our flights and I'm thinking about our bags and what we're going to leave behind.  Ok, I think I actually think more about what we're going to take.  William's clothes, our things, what about the 2 pots that we brought back from Argentina, what about all my books!?  We just found out that our weight and baggage limit is less that we thought.  Luke doesn't have a problem with this, but well, I like packing everything up so I'm already  thinking that this could be a problem.  Luke likes to remind me that we don't need to carry everything with us.  Ahh.. travel.  And now with a baby.  This could get interesting!  Hope you all had a good Christmas.
