Welcome @Kitties, as has been said, there’s a true mix and match of parents here and, whether we sit side by side doing their revision with them, or we simply deliver copious cups of tea and regular meals, we all have the same end goal - for our children to do as well as they can, all things considered.
Personally, I have had no choice but to closely support my DD due to severe ongoing health issues which are proving an absolute nightmare to manage right now. It’s the least I can do given her stoical approach and utter resilience throughout her schooling. That said, she’s been self studying and I’ve only become involved when requested. She’s mainly asked for my guidance on what to do, how long for and when to rest more than anything else.
If I could simply offer the water bottle and pencil case at the door, I would, because I feel that’s just as supportive and just as important. It’s all down to personal circumstances and individual needs of our DC.
So, you’re very welcome here and I’m glad your DC managed to leave with both water bottle and pencil case in their possession!
