I've just been to pick up DS from nursery and on the way home we stopped at the park. There was another mother there and she had a toddler with her, I'd say he was probably about 18 months, maybe a bit younger. Anyway, she wouldn't let him go on the swings/slides or anything, but instead she was throwing sticks for him and telling him to fetch them! Like one might do with a puppy? I just found it really strange, any thoughts?
