Swimming again

This term I've enrolled Eb in swimming lessons again. So far it's been great for her, although we missed the first week and will miss another 2 weeks during term. She loves the water and is coping very well - although at this stage I need to be in with her. She is really struggling with me not being nearby and I'm not sure what to do about it. She settles beautifully after a few minutes - but she just freaks out if I try it without me in. I guess it will all settle down. She's back the same at Kinder - although, once again, she does settle soon after I leave.
Here's a photo of her last lesson......not a very good one I'm afraid!
