Just to offer an alt perspective to @converseandjeans- I have a child who can’t play alone.
I persevere with it.It does nobody any good to have a child who can’t play independently.
To offer an example .
Today DS 4 was taken out at 9am and had complete 1-1 attention and outdoor activity until 2pm. (Hiking, small bouldering, play area, stream paddling, and mini bug hunt).
At 2pm we’ve come home and I’ve asked him to go play alone in the living room for an hour while I do the laundry, wash up and prep dinner in the next room.
He has 4 boxes of train set, jigsaw, small world toys and a book case. I’m talking to him. I’m calling him in to help with jobs he likes (eg mixing Yorkshire pudding batter).
He is VERY cross that I’ve asked him to entertain himself for probably a total of 40 mins out of 60.
But he’s had 5 solid hours of 1-1 attention and physical, emotional and mental stimulation.
Now I need an hour to make our lives work- clean clothes, food etc.
Sadly, as I’m a LP, he has to lump it if he can’t like it. And he does NOT like it.
Some kids are just high needs, and no amount of “wearing out”, attention or otherwise will cut the mustard for them.
