I think it depends on what you want to do in terms of do you want to go on outings with your child on the days you have no daycare kids or do you want to start a side business knitting hats in which case having one child for your own daughter to play with while you knit for an hour each day whether you have only one other or some days have two others is up to you but think about what your daughter will be doing while you are doing whatever it is that you want to do - does she need a playmate. Maybe she would love gardening with you one on one and maybe she would prefer to play on the climber or in the sandbox with a friend while you prune the roses.
