2 year old swore at nursery today :(

[Worriedmummy72]

I'm beside myself - my DD is 2 and attends Nursery full-time, today I've received a phone call from the key worker to tell me that she's punched another child in the face randomly and she's been sitting on the floor saying the F word :( I NEVER EVER swear - anyone who knows me knows I am the biggest prude, so I have no idea where she has picked it up from because it is literally just me and her at home as I am a single mother.
For context though, she's recently started seeing her Father again through supervised contact at a contact center and he was extremely violent towards me and we're currently going through Court proceedings. I don't want to make an immediate link to that as I know at 2 years old there are major development changes, but I am beside myself. I feel so upset - my DD is such a good girl at home so to know this has happened makes me devastated, the keyworker said her behaviour has regressed significantly in the past 2 weeks :(
Has anyone ever been through similar with their child?

My daughter is 2 only goes to nursery part time but they told me she was smacking other children but they just said for us to work together telling her no. I was mortified when they told me she'd been smacking. they said it's normal for her age. They've said she's started saying no alot too but she hasn't sworn....yet. last week they called me to pick her up because she was having the most epic meltdown ever, as in angry writhing on the floor, trying to intentionally fall out of people's arms, running away from people, screaming top of lungs and trying to bang her head on the floor. I had all the parents lined up outside watching me trying to console my child who was just completely inconsolable at that point. I was so embarrassed.

I'm not going through court proceedings and haven't been with anybody violent but I guess just keep reinforcing it's wrong to hit like what I'm doing with my daughter. I understand that it makes you feel awful when nursery staff tell you your child has done something wrong but I guess they have to tell you. The punching may not necessarily be to do with her father, it could be speech. I've got no idea what your daughter's speech is like by my daughter's isn't developed properly yet so she gets really frustrated sometimes as she can't explain how she feels. Did her keyworker say why she thought it happened or what the situation was? It's hard for us to know what happens at nursery as we are not allowed in anymore xx
