The previous noises that April slept through were steady, mechanical sounds that were more like white noise. Of course the sharp ringing of the phone wakes her. Me personally, I would have put her down in the crib the moment she dropped off and taken the weight off me. I could carry a baby in a carrier for only so long before it started to hurt my back. Carrying around April while doing all those chores clearly indicates that Elly has a much stronger back than I did.
