DD8 declared herself vegetarian about a year ago. It was mildly inconvenient at first as none of the rest of us are, so making meals for me, DH and other DC is a little challenging, but it’s fine.
Vege DD has been very committed and hasnt doubted her choice at, she won’t eat gelatin in jelly, sweets etc. Also won’t eat any meat substitutes like veg sausages or quorn.
She is quite fussy but we think she’s still eating well - lots of veg etc, plenty of dairy and nuts, plus chickpeas, lentils, some beans. Also a daily kids vitamin/supplement.
MIL and SIL cannot get past this and speak to her like she’s stupid about it, or to us in front of her eg. “Well why is she like this?” “Where has she got this from?” (quite accusatory) “How ridiculous!” “Your making rod for your own back here letting her call the shots.” “You should tell her no.” “It’s not healthy/right.” “You should her this/that/the other.” It’s like they think she has some illness and that we’re idiots for ‘allowing’ this.
I mean being vegetarian isn’t my bag but if that’s what she wants and she’s eating what I think is healthily, I don’t think AIBU am I? Well I guess I know I’m not really, but other parents have been a little eyebrows raised or they laugh and ask if she’s grown out of it yet, so maybe IABU
