At ds's gymnatics class, the parents all wait upstairs and watch from a sort of balcony. There aren't enough seats for everyone, so unless you're slightly early (almost never happens in my case!) you can't be sure of a seat. A lot of parents bring other dc along with them, so there are often several children in seats while adults are left to stand. This week, one little boy (approx 3-4 yrs) was alternately sitting on the floor/standing but had put three soft toys on his seat. I'd had an exhausting day & my back was aching from standing up for so long, so I asked the dm of this child whether I could sit in the chair occupied by the soft toys. She said, "Sorry, no, we're using that." AIBU to think that small children can sit on their parents laps in situations like this, and that adults should be offered a seat?
