I used to offer this, but found it just 'messed up' for lack of a better word our day and threw off the other kids. The little one couldn't handle coming once in a blue moon and cried the whole time. My regular guys had no use for her lol. It ended up being the most frustrating days and experience for all involved. The mom however, still wanted to continue sending her as she liked her 'alone' time even though her child was not tolerating it well! I no longer offer it and have a minimum of 2 days/week for anyone wanting care..and even that is hard sometimes for the child to adjust.
