As one of my DS says "I wish the virus had never existed, and we could do everything like before".
Sadly that wish doesn't seem likely to be granted any time soon.
So back in the real world...
Schools are barely reopening in England, and that doesn't cover yet my kids' primary year groups. No clear plans from the government aside from vague aspirations. SAGE advice seems to suggest rotas. Scotland is planning blended learning... Other countries in Europe (the ones which have reopened) currently seem to favour teaching kids part-time, in order to keep classes small.
AIBU to assume that when schools do reopen for other primary year groups, it will NOT be full-time at first, and plan my life accordingly (e.g. when considering how best to use my annual leave, whether it is worth investing in home-learning resources such as laptops, whether I should spare some time to look for a nanny/baby-sitter, etc.)
Please note: this is not about what I want, or what would be the best policy, but about what seems most likely to happen.
