Mainly because it is so often aimed at parents who deal with their DCs in a similar way to me. I have a laissez-faire attitude - I freely admit that. We are quite relaxed on food, bedtimes, who they play with, where they go. But so far, I seem to have 3 well-behaved, considerate, lively, interested, independent DC who behave well in school.
My default response to 'can i have/do/go' is 'we'll see' or 'yes'. 'No' responses are few and far between. This means that my DC will argue the toss sometimes, but I think that's OK. If I have a good reason to say no I will give it and they have to suck it up. But I won't say no unless I can give an explanation. I know parents in rl who say no so consistently and firmly that their DC never ask for anything 'because Dad will say no'. Now I think that is very sad and, if there is such a thing 'lazy parenting'. To train your children to expect a negative response so they don't ask. How much easier can parenting be?
I have no problem with my DC arguing with me. I am the parent so I have the ultimate say so what is so bad about discussing it? It would make life easier not to have to, but why says parenting is easy?
I think that when people say 'lazy parenting' they really mean 'parenting different to mine'. I have 3 DC and in 12 years I haven't had the opportunity to be lazy. I don't know any parents who have TBH.
