I don't personally find her soooooo transparent, I think she's definitely one of the better insta-mums out there, and I very much commend her on that. But I have never seen her talk straight facts on budgeting and pricing and that's why for me watching her travel vlogs (not my thing) are more escapism, as it's not a reflection of whatever regular family lifestyle she 'thinks' she's portraying.
I'm sure she definitely works hard and so does her husband, but their disposable income is a lot more than an average family with 3 children. So much in that house is brand new, a lot of their food is convenience food (in the sense that you're not making any sauce or ingredient from scratch), all their pizzas, take aways are expensive etc etc, they eat out a lot yet still can afford multiple trips a year, and everything "new".
I've never seen her talk about buying second hand clothes on eBay, or charity shop finds, which is fine, I'm definitely not saying everyone has to, but she's not "regular" or "ordinary" in that sense. So I guess I dip in and out of her videos and don't think she's the de-facto insta-mum example of perfect transparency and etiquette, sadly I don't think any of them truly are.
