how can i help my daughter get over her aversion to open mouth chewers? (blatantly not an AIBU!)

[bejeezus]

7 yo dd has come home, more often than not recently, with her packed lunch barely nibbled. She complains that if she sits next to someone, who eats with their mouth open, it makes her feel sick and she cant eat her dinner!

Nobody likes it much do they, but what can you do? Ive told her to just look in the other direction, but she said once shes seen/heard it, her stomach is turned and she cant eat.

Shes inherited this bloody fussiness off her dad im gutsy and NOTHING puts me off my food

there is not much to her and her appetite is not good at the best of times. She really cant afford not to eat from breakfast until tea time.

Loads of kids eat with their mouth open; what can i do?

bejeesus sounds like she is a bit uptight and probably the eating noises and open mouthness is exhaggerated in her ears IYSWIM i wonder if she is phobic about something , so whatever the phobia is its escalated , Think of somebody scared of spiders and they think they are HOOGE , Dunno if it would help to speak to the school about it or the gp
