this isn’t about my daughter but I’m a head of year 11 in a secondary school and I have a student who is known to be very defiant and difficult to work with she is very popular in school and gets along with everyone buy every time she kickes off and I try and talk to her her thumb is in her mouth so I can’t understand her properly . But it’s not something she dose js when she’s mad or upset it’s all the time I go in to her lessons to see how she’s getting on and she’s sucking her thumb often playing with the tag in her coat at the same time I’m just wondering do I say something to her as it can be irritating always asking her to repeat her self because I can’t understand her or should I just leave it
