It can be children who have done exceptionally well in certain subjects, but need more time for others. No, summertime, for most of us, is a beckoning time to go on to new and exciting things, a call to get more accomplished while there's time. But duty calls - there's still work to be done with our children's souls and minds, not to mention the work to get done in and out of the house. We keep up with the basics like religion, reading, and math . For families who can't do so during other times of the year, daily Mass might be an attainable goal during the summer months.
Reading can be less formal, too.
Some people feel they have to read aloud every single book to their children . When they can't do this because of other duties, the reading gets neglected - and mom and dad get the guilties. My opinion is if the older children can pick out a book, they can read it to themselves. The younger ones, of course, can be read to on occasion, even if just to teach them the love of reading. I can honestly say that, in my own family, my parents did not read aloud to us regularly.
