Most homes will have coloring pencils or crayons. In my house we also have glitter pens, foam pens and most importantly paints for the kids to select between. Using paints will require a little bit more setup time as you may need to clear an area and lay newspapers down over the table to protect it.
As she is leaving, her final request is often for me to print a few more pages for her to take home or even a large batch so she can share with her friends when they visit. Of course, as always I am too happy to oblige. Especially as it's so cheap to print them out. Few things are so cheap but can still make a child so happy these days.
Batman cartoons are great, and they always seem to be on. There have been many of them over the last few decades. Best of all, every time they bring out a new one they seem to tweak the formula and keep things fresh. For example in the latest version called "Batman - The Brave and the Bold", Batman is a little less serious, while in previous versions of Batman cartoons he is seem as a very stern and serious figure. But best of all, there is a wide supporting BatFamily, so even if your child isn't big into Batman, there are other cool characters like Robin, BatGirl, Nightwing and the toys like the Batmobile, Batcopter etc. There is really always something for everyone when looking into Batman Coloring Pages.
