Why are balloons harder to inflate when you start, and feel easier once they start expanding?

I mean your average party balloon, when it’s completely deflated, it seems you have to put extra effort into getting it going. As soon as it starts inflating, you need less effort.

The volume increase of the balloon decreases for each inflation as it gets closer to its maximum capacity. The resistance for each inflation also grows as your get closer to the maximum capacity. The first blow has the least resistance and the last will have the most since the tension in the rubber is increasing for each inflation.
