I couldn't imagine caring for others when my own was only 2 1/2 months! Her brother (25months then) was WAY too much to handle lol! Now that they are 10 months and almost 3 I am starting to care for another child but at 2 1/2 months... while the older one was adjusting to having a baby sister, no way. So I don't think anyone would not fully understand that you have limits, and this may be it. Good luck!
