Yet another anecdote here but I have an 8 year old that had a "covid kindergarten" as her teachers call it.
She's now about to finish 2nd grade and is doing a summer reading program with her school because she's in the ~40% percent of her grade that are behind state standards. As her parent, I almost feel helpless here. I want her to enjoy reading. I try not to push her "too" hard at home to the point where it's a constant fight.
