wiy- picking your yogurt when your baby starts crying is not neglectful. If the baby was in pain or had been screaming for 5 min yes, but an infant doesnt have to be picked up the minute he starts crying.
If the baby could have been hurt by what was put around/on him, then it would upset me. If the baby was in a big puffy snowsuit and she put a bag of lollies on him, nope doesnt bother me. Not that i would personally do it. But i have put light groceries next to a baby sitting in the stroller
