OP, the thing is, I am envious of people who can spend the summer weeks with their children. I would love to take the 5.5 weeks off for relaxed times and day trips.
What i’m saying is Envy is natural . We are all envious of nice things we wish we had.
But dwelling in it can bring us down.
You have a hell of a lot in your plate and running yourself ragged doing another job isn’t really going to help.
The summer is for picnics in the park, day trips, relaxing.
Plan to visit a different park every week. Make plans with friends. Look up seaside day coach trips.
We didn’t have holidays as kids, we had day trips to the seaside with s pack of lettuce and salad cream sandwiches, and Mum showing us how to dig a speedboat in the sand and use seaweed to make a decorated sand birthday cake.
Go to woodland, check out every free museum and use your Tesco points to the max for activities.
And whatever you do, don’t go camping in October. (I say this as a keen camper. It isn’t the time to start and comfortable camping requires considerable outlay).
You are a great Mum. Providing a hol or not is not part of the judging criteria for parenting.
Being there for your kids and giving them the capacity to enjoy the potential of the world they have is.
