I hope she's local. You need to take her out to coffee.
First of all, explain the artistic nature of photography. She hired you because she saw work that you'd done. And to do your best work, they have to give you some freedom. Otherwise you're just regurgitating the crap they sent you from Pinterest.
Second of all, explain to her that if she plans her day like that, as soon as a single thing pushes the timeline 1 minute late, everything will get throw off, and a timeline that she built and designed won't even matter anymore. She'll feel rushed, and stressed out, to get back on track, instead of enjoying the day.
Now explain to her that you do everything you can to capture every moment. Ask her to trust you. As her to make a general timeline with notes about when things are going to happen, and have her give you an extensive family shot list, and more importantly, a brief and short "must have" shot list of out of the ordinary things. Usually a list of 3-5 things at most.
If she can't trust you, you may want to bow out of this one. This is a huge recipe for disaster.
