You might have a rose-tinted idea of women's football if you think it was so far fetched. It IS an often aggressive, contact sport, and those of us who play it understand the risks and take it seriously.
I've seen more broken bones and soft tissue injuries than I can count, and had many myself. When I was playing more seriously, on average every 18 months I'd have an injury that would take me out for several weeks (broken bones, torn tendons or muscles etc).
Injuries are more often caused by accident or cynical, borderline tackles than from outright violence, but that does also happen. A close friend was elbowed in the face during a corner kick and ended up with a permanent brain injury.
The baby scene is simply showing the balance between childcare and playing commitments - something very many women face. I've seen players come off at half time to breastfeed their babies. I've seen many players face up to the referee when they disagree with a decision (the incident in the film was pretty tame) and get yellow and red cards.
I've also seen women play in very short shorts. We used to only have men's kit play in, which was enormous, but now some makers of women's football kit seem to think we want to play in bikini bottoms.
