My son only seems to be engaged with interaction with people. That’s great but not always possible. He doesn’t seem to like any toys and they often frustrate him, for example if he’s finding it hard to grab something. He also isn’t happy just independently exploring on his playmat, But I do need some time to go to the toilet, cook, put laundry on etc and it would be good if he could play alone, just for like 10 minutes. Any recommendations?
