Congrats to your daughter on riding a roller coaster! She is braver than I am.:)
With her reading, just keep modeling to her when you read aloud. Make sure she's sitting by you & reading along with you so she can see the commas, periods, etc. and know why you stop, pause, change your tone, etc. Be patient and keep it fun and light-hearted. Also, keep the reading sessions short, just like you're already doing. One more thing: audio books might be good for her to listen to & hear fluent readers while she follows along in the book.
