My 5 year old’s stutter just got suddenly worse, about twice as much

My 5 year old’s stutter just got suddenly worse, about twice as much She’s had issues with speech since she started talking and has been in speech therapy for over 2.5 years. It began with her having a hard time starting sentences, for example she would drag out the first word of each sentence such as “weeeeeeeeeeeeeee should go to the park today” the only word that she would be stuck on was the first word. Now suddenly like the flip of a switch, she’s more like “daaaaaaad daaaaaaaad daaaaaaaaaad we weeee weeeee should go to the park today”. It’s like she’s having trouble “taking off” with her sentences, but once she takes off she’s good. We havnt been really mentioning it to her but we have noticed the change and are going to bring it up at her speech appointment this week.
