My advice to all teen parents - not that anyone is asking, but here it is anyway! - cut off the electronics. No TV or computers in the bedroom, no video games, limit their time with the phones. It's for their own good. BORE THEM TO DEATH and they will eventually come out of hibernation.
I work with high school students and the addiction to the phones and video games is the number one problem we deal with every day. We have students who will confess that they never sleep at night - they are up playing games or texting/snapchatting/instagramming all night long. We have students who are on their phone IN SCHOOL all day long - if they aren't using it to communicate with someone, they are listening to music with headphones in their ears. How can they possibly be learning anything? When the phones get taken away, they go into an absolute rage - just like a drug addict who can't get a fix. Cut them off and suffer with them for a few days and eventually a real human will emerge.
Kids NEED nature. They need to be connected with the earth and with living things. If nothing else, they need to be mowing your grass or weeding your flower beds or spreading mulch for your neighbors... get them out in the sunshine and get them busy. They will hate you for it, but will eventually thank you. They may be 20 or 25 before it happens, but eventually they will realize it was for their own good.
