I love technology, but I am cheap. So I finally bought a phone with a slide out keyboard in November and upgraded my calling plan to include unlimited text. Oh and my husband and daughter got phones and unlimited text too. My husband and I text all the time now. Our oldest daughter doesn't text much, but our younger daughter (who doesn't have a phone) can't wait. She texts for me whenever I will let her. So I know she will be a texting fiend when she gets a phone someday.
That is why I found this guidance about setting limits with texting so helpful.
