First and foremost, do you need the money? If yes, than this might be a great way for you to see all of your childs milestones, and keep him in your home. This is the choice that I have made, and for the most part I do not regret it. I have over extended myself, and allowed my family to depend on me for more than I should have to give. I have 4 kids of my own, and currently keep another 4. That is too much!! But I will be downsizing at the end of this school year. But, in my opinion, and 12 years of experience, it should not really cramp your style. You need a double stroller for sure, but you can still head to the mall, go to the library, even head to the pool. IF, that is your personality that is!! You need to lay out some expectations, in writing, and then stick to it. I say you could charge around $150 per week, or even a little more. You need to discuss what you will do when she takes a day off( she should pay you regardless, unless it is a scheduled vacation). Or what about when you need time off. She should have someone she can call in case your son is sick. You should be paid on the Moday morning of the week you are about to be working. And, what will you do if she needs him to stay later than usual? And, of course, it depends on her personality too. Your parenting styles need to blend. This is a lot to think about, but it is a good way to make money if you need too, but it is a lot of work, so be careful about the decision!! Let me know if you have any other quesitons! ~A.~
