There is no single "right" way to do it.

Parenting that is, rather than any other type of "it" you might be thinking of.  I'm new to the world of blogging, I've only been blogging for a month or two - I don't even have any followers yet - but already I have to say that I have been rather taken aback by the judgemental attitude of some bloggers (non of which has yet been directed at me I might add, I wait with baited breath for that joy).  These are other parents who really should know better than to judge others when you have no idea what goes on in their lives.

Despite being siblings....

It doesn't seem to be a particular "type" of parent who is critical, I've heard attachment parents who claim that they are soft and gentle types ripping into people who dare to do it another way.  I've heard the other end of the spectrum poo pooh attachment parenting and its values too, with all the in-between.  I've spent a goodly part of my week attempting to remove one particular blogger (with her moaning and rants) from my reading list to no avail (if anyone can tell me how to remove her, I'd love to know, I've tried all the obvious ways!).

...they are all so very different...

There is no "right" way to parent.  What works for one family, may well not work for another.  What works for one child may well not work for another, hell, sometimes it doesn't even always work on the same child in a different situation!  I find it frustrating when people offer well meaning, but rigid, advice.  "Oh well, I just do this!", as if were a cure all panacea.  Yes, it may work for you and for your child in the situation that you are in - it may well not work for another.  The more children that I have, the more I have realised how flexible you have to be to your individual child, particularly when you are parenting a child on the Autistic spectrum.  There are many different ways to bring up a happy, confident, well mannered, well rounded child - no particular method has exclusive rights to it, if it did, we'd all do it that way.

...and require different methods...

My children are, in general, pretty happy, bright and well behaved - I have not "damaged" them by leaving them to cry on occasion, nor have I "spoilt" them by feeding them to sleep and carrying them round in a sling.  I may not do the same methods as you, that does not mean that either of our methods are "wrong", they are just different.  Different methods suit different families and different children in different situations.  So leave your judgey pants at home and put away your judgey stick.

...to bring out the best in them!

I'd just like to add (to the end of my anti-judgement rant) that there are some absolutely fabulous blogs out there that offer great advice without judgement and others that have amazing ideas which I can't wait to try out - I'd hate to tar everyone with the same brush!
