Yes.... yes.... oh did I say YES!
I met my partner (now husband) when his son had just turned 4, he was the sweetest nicest little boy, DSS now lives with us, for the last few years, this year he started secondary school. And has become the nasty, cheeky, disrespectful and aggressive.
He shoved me into a door last week because I wouldn't give him his ps4 remote before school. This was the first time it was witnessed by my husband, he has behaved in aggressively towards me out of sight of my husband a handful of times now (my husband never believed me, im not sure why) anyway his dad went mental! I've never seen him lose it like this. Gave him smack on the arse (i know many will thibk this is bad, we dont agree woth spanking my husband was in tears afterwards) and a very very stern lecture of putting his hands on a woman....any woman!
We cannot understand where his behaviour has come from, it's just strange he woke up one morning in summer and just because horrible towards me in particular. His dad has since sat with him many times and asked whats going on but he just says nothing, and "she did my head in, i should be allowed to do what i want" or " she aint my mum she cant tell me what to do" my husnands response is no biologivakky she isnt yet she has done everything for you mum does since the day she met you, she loves you unconditionally, he replied "it don't mean nothing"
we asked the gp for an appointment to discuss options of talking therapies, may seem extreme but we all want this nipped in the bud now
I know this is a rare and extreme case but yes I miss my dss being a small kid.
