I've started keeping a spare box of diaper wipes at the table (and others around the house!). They make easy wiping cloths and they're made for skin. (We use the Huggies w/o any perfumes.) In the summer when she gets extra-messy b/c she's also sweaty, we'll do baby powder (corn starch, not talc) on her neck and chest when we change her in addition to the diaper area.
