I too do communication books, they are small spiral notebooks from the dollar store, I only write outside time , lunch and nap details ....takes about a minute and a half per book and I do it while they kids are eating.... If thechild normally has a bm at daycare and doesn't on a certain day I write that in and I use it to let parents know of needed supplies ... My parents sign each page so I know they've read it and they can let me know of any thing they feel is important as well
