Scaling up — how do you manage initial slippage with larger sizes?

Been trading micros on a prop firm account for a bit, doing okay. Now looking to move to standard lots on some pairs like $EURUSD. My concern isn't the capital, but more the execution. I've noticed even on micros, a market order can slip a pip or two on faster moves. How do you guys manage that initial slippage when your risk on that trade is suddenly a lot more substantial? Is it just something you factor in, or are there specific order types or strategies you use to mitigate it?
