Do you have a monitor? I wake up if my baby coughs in her sleep, and I can sleep through almost anything. I think mothers are programed to wake up when they hear anything from their kids lol. DH on the other hand, won't wake up at all. I could have the monitor up to full volume and let the baby scream (not that I would) and he'd never hear it. I honestly don't think you would have any problem with waking up when the baby cries.
