I used to get stressed when I was at that stage op! So I hear you!
Now we are past that stage I can see that me getting stressed didn’t really help matters 😄
In my experience , children take their cue from you! So if you go around apologising saying or even thinking “oh sorry this isn’t more exciting”. and “are you bored?” and “I wish we had the opportunity to do (something else)” then they will have that attitude and behave as if they are bored and dissatisfied!
If you can be more confident op and act and think in a more positive manner, “isn’t it great we have this time together”, “it’s so nice to be able to chill out as a family”, “I am really looking forward to board games tonight” etc etc they will -more or less - accept that everything they are doing is normal and good.
You don’t have to be Pollyanna-ish about it, but your dc are lucky to have you as a concerned parent, and a safe home etc. And it is good for children to get bored occasionally as, given the right encouragement and tools, it allows them to be creative and develop their inner resources.
We alway used to have a few holiday traditions and projects going on … learning something new … board game night … children cook night … that sort of thing?
Sometimes a glass jar in the kitchen on which they have written their favourite 20 minute activities can help in those “what do we do now?” moments.
What is your 12 year old interested in? Trains, wildlife, models, sport, reading, art? Ask him what he is interested in, off screens that is, and try and facilitate his pursuit of one or two of his interests? Or if he doesn’t know, introduce him to some new hobbies? Take him to an ice hockey match, or teach him to play chess, or visit a climbing wall?
An eight-year age gap does make it more challenging so I agree that one-on-one time with the eldest twice a week would be good once your youngest has gone to bed. Surprise him with some trips out as soon as your dh comes home. You could take him out to the cinema or for a bike ride. It doesn’t have to be fancy.
I would also invite his friends over twice a week to hang out so that he has some companionship his own age. And that’s when you can give your youngest her one-to-one attention.
I used to try and go on one “big” expedition a week as a family during the holidays to a local attraction or beach or park. Or just get on a train a couple of stops. You can start giving your eldest some responsibility on these outings like finding the route, researching the activities, planning the agenda, buying refreshments, budgeting.
And then I would try and do one smaller local trip like a picnic in a park, or table tennis at the leisure centre.
By the time you have had two trips out per week, 2 lots of friends to play, one board game evening, one afternoon out with dad, one pizza and film night, the week soon starts to fill up. This all takes energy though so make sure your dh plays his part.
Good luck op! You have a lot on your plate but please remember that you are enough! Forget social media and what other families are doing. Have confidence in yourself! You sound like a lovely person, and your dc are lucky to have a very conscientious mum who cares about them. Please don’t be too apologetic about what you are offering! They are lucky dc! 😀
