This is the first year that I did feel like I needed to do a slight revamp of our curriculum/schedule around this time of year. This year, I made our plan and we have stuck with it.
It certainly makes it easier on the wallet when you aren't having to re-buy things. I think it helps that I am using many of the same type of resources that I've used in years' past, so I already knew that it worked for me and my children. It also makes a difference that I'm used to homeschooling, the kids are used to homeschooling. It also makes a difference that we do all the schooling for everyone in basically one big space and I can come easily come over and help Jelly Bean during her morning seat work. And it makes a difference that the younger children nap in the afternoon and I can do more teacher-intensive subjects with Jelly Bean then (and Super.)
The only very slight tweak is that I had to re-do some of the preschool shelves, especially on the bottom shelves. The infant that I watch is getting increasingly mobile, as well as spending more time awake and out with us, so I had to move some of the things that I didn't want her to put in her mouth, etc.
