Long sorry ...
Just had another trip out with the DC end in tears 
DC are 5 and 3 . I took them out for breakfast to their favourite place this morning . No problems until we went to the toilets after.
Just general messing about , touching things and not listening whilst I'm trying to help each of them get sorted / hands washed etc.
Then we went to the park and this is where it got frustrating .
I was pushing both dds on the swings - there wasn't much enjoyment from any of us as they just kept whining to go higher / push me / not like that / do it this way / you missed me. Every bloody second .
Needless to say I got frustrated and told them one more go each and tried to show them how to swing themselves .
Oldest dd went in a huff , refused to try and said she wanted to go home and that she wished daddy was here
(DH is away with work) . This is typical of her - huffs when she doesn't get what she wants , when she wants it and then turning mean.
I told her to stop spoiling stuff and she had hurt my feelings .
Both dds eventually managed to get themselves in to a game and played nicely together for all of five minutes !
I then had to police the taking of turns on the slide .
I also had to push them on the roundabout - I wasn't allowed to sit on it though - I had to stand and push them 
We eventually have another go on the swings before we go home - more push me push me! . I gave them clear warnings when there was 5 minutes , 1 minute left etc.
Time to go and dd2 refuses to get off the swing . Tries to negotiate extra time and is clinging on. I tell her I'm going to pick her up and literally have to drag her off the swing 
Obviously , now we are in tantrum mode and she sits on the floor refusing to move unless I carry her to the car - which is just a few metres away ! . I can't carry her as I have back problems so I say, ok I'm off to the car and turn my back on her .
She screams "I hate you" and cries and screams back to the car - giving the whole park some entertainment.
FFS ANOTHER attempt at trying to do something nice with them turns to shit .
I feel like all I'm doing is telling them NOT to do stuff - I was hoping the park would be a place for them to just run around and let off steam .
Would you have stood and pushed them over and over on the swings ? Was I being mean for not doing as they want the whole time ?
Surely in a small playground , they don't need me to helicopter them by now ?
This kind of thing happens all the time . I hate swings because of this very reason
