Very sweet!
Moms just get used to juggling many things at one time. I guess we have a built in mechanism that gives us the ability to cope and to multi-task.
We can be in an upstairs bedroom busy - cleaning or whatever - and hear what's going on with a 3 yr. old in the living room, while the husband/daddy sits in a recliner in the same room reading a paper totally oblivious to what the child is up to. Amazing!
