I was raised by a WW2 child. She was born pre-war and grew up not knowing what peace was. She was bombed out twice in fairly close succession around the age of 5. When the war ended, there was a decade of gradually fading rationing before the final restrictions ended. Her father who came home was not the man who went off to war, permanently damaged by trauma and injury.
Generally, she's ticked along fairly decently for the past 80 years... apart from the hoarding disorder that's really caught up with her in the last 25 years triggered by trauma and scarcity.
Should she have been more resilient?
Covid lockdown was very much not like her war experiences. Ironically her happy memories of that phase of life are about her extended family pulling together to get through incredibly difficult times, precisely what was made illegal in 2020/21.
My DCs' granny lived abroad and had a life-limiting condition when we had our last scheduled family visit in Oct '19. 2020 was a write off. By a margin of one week with the extended restrictions we managed to travel to see her in 2021... well, due to care home restrictions only DH was allowed in. By 2022, she was ailing rapidly mentally and physically. By the time carehome restrictions finally eased, she was weeks away from death and unable to recognise her grandchildren even if they weren't radically grown in 2.5 years. They saw her in her open coffin where by the wonders of make-up and clothing, the undertakers made her look impressively like herself as the DCs remembered her. DH felt it would be more traumatic to the DCs to see her last dying weeks at age 9 & 11 so radically deteriorated from how they remembered her from when they were 6 & 8.
Fortunately for DH, he did see her more as solo travel was logistically simpler to arrange last minute for 1-2 nights when she was unpredictably moving between home/ hospital/ carehomes.
The general effect of prolonged restrictions and our long distance families is that our extended family connections have weakened as several branches of family have had lifestage gear changes and that's created fractures rather than gentler, organic transitions.
My DCs aren't traumatised by this, but they have lost a significant chunk of access to extended family life at the age where the strongest memories are often made before getting to the more individualistic transition towards teenagehood, and they've lost meaningful bonds with family because they couldn't have in-person experiences for so long.
Another layer beyond legal restrictions was the effect on peoples' confidence, additional barriers they put up and just the general level of burn-out across the population. Quite a few of my extended family members were risk averse, then in 2021-22 I hit a burn-out phase from the effort of trying to keep my DCs' life ticking over as normally as possible, having my routines eradicated or switched on/ off at short notice for 18m then being hit by a series of bereavements in 2022.
My friends had experiences such as trying to WFH with a toddler on their lap and a young child doing school work at home. We burned out from different triggers, and had nothing spare to really reconnect and add extras beyond regular routines until 2023 when there'd finally been a run of stability.
The effects of prolonged and rapidly shifting restrictions were complex, and some quite subtle and varied from individual to individual and it took a long time to feel a confidence in stability again. We didn't end up with that "New Normal" thank goodness but for many the axis of normal was long term or permanently shifted by a few degrees. For children of any age, their development stage and life experience was different coming out of it than going into it.
