My middle dd is 13 and I have noticed recently her posture isn't good. She's hunched over, rounded back and shoulders forward and tense looking. When she's sitting down I encourage her to sit properly in the chair which she does when she's eating but if she's on her phone etc, she swings round so her legs are to the side of the air and she looks very hunched.
I'm worried it's going to cause problems later, so are there any activities she can do which will help? I've thought maybe yoga or pilates? She used to do ballet which she dropped a few years ago but might be willing to start it again.
She also has pronating ankles and wears orthotics. Is there anything that will help strengthen her ankles?
