I am middle class, I think, but find the overtly 'darling, sweetie' set of parents particularly painful. Obviously bad/good parenting isn't reserved for any group or set, but I have only noticed middle class parents do the 'push my child first, I couldn't give a crap about fairness' sort of parenting.
EG. Today my 2yr old at a picnic with pre schoolers and their younger siblings. (dc4 was celebrating last day at preschool.) I gave dc5 my phone to flick through a story so I could eat my lunch and could stop running after him. Another child, boy aged 4, called (let's say) Jim wanted the phone. I said no as my dc was looking. He could look too. He tried to snatch making my dc5 upset (in that screamy frustrated 2 yr old way) Jim's mother says "you can share Darling" as Jim is crushing my child who is half his size, she deosn't ask him to get off. Now my dc is crying, she says "share Darling, come on" (I'm not sure who she is talking to) So then awkwardly I have to say "Jim you're crushing dc5", he tries to take the phone. So I put the phone back in my bag...."I want that phone" Jim says. I say "no it's away now". Jim pushes into me and punches me full force with both fists. Mother says FUCK ALL. Not five minutes later she tells him what " a good boy" he is and "so gorgeous" she could eat him Darling sweetie. She's so proud of his behaviour at the picnic,.
EG. DC5 gets scratched on the face with a stick, by a 4 yr old looking straight at me. Mother sort of shrugs and says nothing.
DC5 later on a bit cross and kicks a nearly empty bottle over, sheer naughtiness and devilment, before I can even speak mother of stick weilding child shouts "for goodness sake DC5" then spots me and says sorry. I was so fed up by this point that I just said "to be honest I expect nothing less from X parents" and left, in the knowledge that I'll never see them again.
EG Two little girls tell DC5 to get off trampoline saying 'it's ours get off', DC5 complies. Then I give him his football.....they come over shouting at him to share, but as he's only just got it he wanted to kick it first. I just found myself supporting my son in not sharing, even though I think it's important to share, I'm really cross with myself.
This is my last child. I have spent the last ten years watching my dcs play fair, take turns and be generally kind only to see the other mc brats not only put themselves first but parents whole heartedly endorse and encourage this behaviour.
I do know lots of other nice mc parents, but this type of parent is completely reserved for the middle class slightly older mother.(AGAIN to reiterate this is not all mc parents.)
