They absolutely did not suffer psychological damage from being with their own parents!
We played, watched films together, learnt together and spent quality time together - But then i actually like my children!!
I will preface this by saying that I think schools must close at this stage, but please do not scoff at other's dc having been damaged by the previous closure, or suggest that if they have it means their parents don't fucking like them.
I like my dc. I have 4, the eldest has Sen and can be violent and unpredictable. He found the beginning of the last lockdown so hard and had several serious meltdowns. I am a single parent, so while I shield the younger ones as much as possible I can't completely, and eldest is now bigger and stronger than me. It is traumatic for the younger ones to see their brother lashing out and talking about harming himself.
One of the younger ones has developed anxiety issues with the transition from home into school, such that it now takes me up to 40mins to leave him into school each day, which persisted from Sept-Dec. He had never had any issues like this before in 4yrs of previous schooling.
All of my children have anxiety that they didn't have before, to a greater or lesser extent.
None of this is my fault, and it does stem from the breakdown of their routine and world from covid and school closures.
I know that my children are not alone in this. None of this means schools should stay open regardless, but please don't dismiss the psychological damage that other dc have suffered, just because you're lucky enough that your dc has escaped it.
