possibly, but then again she was very vague about explaining the concept of death when Lucy died, as she said then that ethan had lots of questions that she didn't know to answer. she probably fobbed him off when nanny joyce died with nonsense about her living in the sky amongst the clouds and rainbows - despite the fact she has very clearly stated that she doesn't believe in heaven or the afterlife, she would definitely opt for fantasy and fiction over age-appropriate realism. given that she still tewats the kids as toddlers, and that was how she explained death to toddler erin, i expect seven year old "toddler" ethan was brushed aside with similar bullshit when nanny joyce died, babs focused. on running her hands with glee at the content she could create and the sympathetic comments she would recieve - exactly the same reaction as when Lucy died and the Queen! she sees *content* flash before her eyes, and milks it for as long as possible. it's a full forty-eight hours later, and while other influencers have moved on to sharing posts about the announced bank holiday, babs is still taking full advantage of the Queen's death, posting about feeling "wobbly" and her kids "tiny hearts" and handing out advice about the importance spending the weekend comforting yourself, watching TV and eating sugary treats - solely because watching tv and downing sugar is what babs does when she needs comforting, which is literally every single bleeping day!Her Nan died a couple of years ago and she was Erin and Ethan's great nan so they have experienced the death of an elderly relative before. They were both younger then and I'm sure they would have had it explained to them. She's just using it for content which makes her both despicable and vile.
if ethan did receive a nonsensical explanation of death when his great grandmother died - which, realistically, he very likely did - and babs has refused to answer any of his questions since, despite the death of both the Queen and his beloved dog, the poor kid is probably incredibly confused, being nine years old he is smart enough to know that people don't simply go live in the clouds, yet babs is apparently unable to act like an adult, and answer his questions sensibly. i very much doubt that ethan is asking any questions that babs "doesn't know the answer to" or is "totally winging" - especially having previous experience as teaching both RE and PSHE! they're simply topics she perceives as too "grown up" and involve topics she refuses to talk about - implying that "death" is a word that should never be mentioned, and ethan should refer to similar situations as "bad times" etc.
ethan is likely the only kid in his classroom who hasn't had the basic concept of death explained to him! top mumming as always, ignoring and dismissing the poor kid, babying him by describing his emotions as "feeling wobbly" and refusing to allow him to express his emotions and talk about how he is truly feeling and distracting him with food and plastic tat! she's an absolute nightmare.
