My 3 year olds is scared of so many things. & Very dramatically. She has a fit with hair wash ( literally lasts half hour where she looks like the girl from exorcist ) fit with hair cut, terrified to poo in potty, terrified to swim/ jump in pool. She’s generally very fussy; hates eating and extremely prickly, calpol etc is a big no; cutting nails is a big no, nose drops are diastase etc overall she’s a good kid but these things are really frustrating. Any tips ?
