I cut an old towel up and made them into wipes (overlocked the edges), just the size I wanted. I find that terry great for cleaning bums - its just so effective cause it grabs everything. I did make some wipes that were flannel one side and terry on the other (overlocked together) so I could choose to use the side that suited me but I always found myself using the terry side.

As for solution, right now I just use water with a drop or two of water soluble lavender in it for my toddler. For baby, I will probably do chamomile tea solution.
