Keep bags of trail mix strategically strewn about the house. You never know when the baby will fall asleep in your arms. And remember, just as rock beats scissor, a sleeping baby beats mommy's empty stomach. (Sleeping baby also beats bladder - until bladder enters the "possibly causing irrevocable damage to kidneys" zone).
On the plus side, my stomach's rumblings are probably helping the baby sink into a delightfully deep sleep.
On the plus-sized side, if I keep forgetting to replenish my trail mix supplies, I will lose the baby weight that much faster.
