How much time do you generally get for fmla for a son with daily asthma?

12 weeks. First, your employer must determine if you are eligible for fmla. You must have worked a certain number of hours for the company, and there are other restrictions (such as whether you have a key position) however, if you are eligible for fmla, you can use it to help care for an ill child, and you don't have to use it all at once. Here are the rules: http://www.Dol.Gov/whd/fmla/.
