Kids keep saying they are burned out from curriculum - how do y’all handle it?

Edit: wow blown away by the support. Thank you to everyone who gave input. I think I'm going to try to be more flexible when it comes to the curriculum. Maybe I went a little too hard the first year...

First full year homeschooling. We live in a highly regulated state and I use time4learning because it covers everything and I find it to be decent. Kids seemed to like it fine in the beginning but are now griping about having to do their work.

Thing is, the t4L only takes maybe an hour or two. Then they both read from a book of their choice. The other learning is hands on stuff, field trips, activities etc.

It's important to me they learn. I feel T4L is the best curriculum out there for us- and I reviewed LOTS of them.

We haven't been following the school schedule regarding breaks. We took a couple of days for Christmas and ange one or two long weekends. I e scheduled a week long break in April.

We're almost at the end of the year and to be fair, they would get like this in public school as well. Wondering if other families go through this and how you deal with it without sacrificing the curriculum?
