I generally devote one space to part time but have had two used this way in the past and yes it is a juggle but also the diversion of different kids each day can be a blessing so it works both ways. The big thing is to insist on the same days each week so one family might come M, T, F and another on W,TH. A schedule that rotates means you have to save the entire week just for that family so it cuts into your income.

It can take Part timers longer to settle into the routine and some never do but then again others do just fine. Depends a lot on what parents are doing with them on the days not with you.

In some areas that is what the demand is and holding out means going with no income. The upside is that for all the hassles the rates for part time are generally higher than for full time so with two sharing you make more money for the space.
