You spent the first half blaming your DSS and then claimed enlightenment, I assumed you realised that its just one of those dramas that as a parent you need to take a deep breath and resolve, but no you have now decided to blame your DH.
Its obviously someones fault and that someone is certainly not you.
This isn't about DS or DSS its about you, not understanding or not being ready to be as a parent.
Enlightenment? Have you RTFT? I have had issues for years with DH being what is called a disney dad.
Today is just another incident in a long line of incidents that stem from DH having zero boundaries with the eldest two, whilst having firm ones with our small ones.
Several people up thread recognise me and know exactly what I'm talking about.
DSS drops his tiny sister on the floor, DH rushes to console him whilst poor DD has just been dropped from about 3ft and hit her head.
If our DS, who by the way has special needs, does something dangerous he gets told very firmly that he's not to do that.
DSS('s) show overt disdain and are ungrateful for the Christmas presents I bought them. DH says nothing.
Our two (almost two and three years old) are made to say thank you.
If either of our two are being naughty in any way DH is very no nonsense. Will raise his voice on occasion.
If either of DSS' are being naughty or disobedient DH doesn't say a word because he doesn't "want our house to be the place they get told off"
My DS broke DH's charger before the age of 3 and got told off -
One of the DSS' breaks several of DH's things over the course of a few months and DH just rolls his eyes and buys another.
One of the DSS' chopped the hair off one of DD's new dolls I bought her for Christmas (and I know it was one of them as my two wouldn't even know how to use scissors)
DH suggested that I probably snipped the hair by accident when removing the doll from the packaging, even though it was in perfect condition until boxing day when the DSS came
Our two are expected to give whatever they're playing with to DSS if they want it (a ball, a tablet device)
DSS is allowed (by DH) to deliberately exclude DS from whatever game we are playing as a family, or prevented from going into his own pop up tent.
There are so many examples, many of which I have discussed on MN, the overwhelming response has always been that I have a DH problem.
I advocate for my children in the moment but have zero ability to effectively discipline or redirect DSS on any sustainable level because DH is hell bent on shielding them from feeling any consequences for their actions.
There is a HUGE double standard at play here.
With all of the above in mind, you'll have to forgive me for thinking DSS shouldn't be allowed to just scream in adults faces - least of all adults that do so much for him.
I could go on, and on and on.
With all that in mind, those on here who think I'm the problem are barking up the wrong tree.
