Most carriers impose a 160 character limit on a text message to limit the transmission bandwith. I don't know if AT&T does this on other phones, but they don't on the iPhone. Thus, your daughter may type more than 160 characters, but Verizon refuses to transmit any more than just the first 160. So you are getting the entire message as transmitted. Tell your daughter to be less verbose while texting and your problem should clear up
