Noticed this a lot with my 12 year old recently. Especially with it being the holidays. Whereas we'd often have days out together to the theatre, cinema, shopping, sight seeing etc he just doesn't seem interested anymore. He would rather be on his phone or out with his friends. Took him on a fairly expensive day out last week and while he made all the right noises and said thank you and so on, I could tell his heart wasn't really in it. Of course I knew this would happen but I didn't expect it just yet.
I have younger dc so often family days out are a bit boring for him but I thought we might manage a few more years of hanging out together while dh has the little ones.
So have you been here yet? How did you feel and how did you manage it? I'm not going to keep insisting he comes on expensive days out if he's not that bothered but equally he's too young to be totally left to his own devices.
