I am a stepchild 4 times over.
I have had 1 negative experience (1st stepmother) and 3 people who enriched my life and my children's for the last one as stepmothers 2 and 3 plus stepfather.
I never minded not being able to say " mum and dad" I had my mother and stepfather it was fine to say mum and (his name)
Different clothes - didn;t happen for me anywhere
Different meal times - did happen but was presented as a positive thing as we were exploring things and I do not recall having any issues with this.
Different snack allowances - happened with step mother 1 I disliked it intently. As an adult I actually think she had a better grip on healthy eating she was just poor at presenting it.
Different levels of freedom - didn't happen for me parents stuck with what freedom child was allowed at other parent
Different expectation around phone/gaming use - many years ago so I shall use different expectation for using the TV stepmother 1 monitored ALL tv use you had to explain why it was good for you to watch (pretty hard for a 11-year-old who wanted to watch dynasty) I hated it. stepdad and stepmother 2 didn't mind what we watched as long as it was age-appropriate.
Different town - with 1 stepmother this was the case.. however my mother was the one who moved away first so again I never minded this. Also dad and stepmother 1 lived in a large town and we in a small one and I used to LOVE it.
Different friends/no friends because only there EOW... yes this happened but I also had my brother there when I went so again I do not recall this a issue
No dance/gymnastics/etc because away EOW n/a
Christmas without father every year Yes this happened however for my brother it was Christmas without mother every year (bro with father me with mother) As an adult I have spent christmasses with my dad. I have only positive memories of Christmas and my dad used to do a 2nd Christmas every year for us all..
Never just saying 'mum and dad' As above.
Having step and half siblings Didn't like 1st step sister she was the golden child who could do nothing wrong. I was blamed every time there was an issue as i was " the oldest" 2nd lot of stepsiblings i grew close to and I still have contact with. 3rd I've never met as my father remarried when I was almost 30
Feeling guilty for loving full siblings more -
I have never felt guilty for not loving my step-siblings as much as my full siblings (I have no half).
Never really relaxing at dad's because only there EOW- this happened with stepmother 1 by the time it was stepmother 2 We were so welomedand the home was a wonderful warm place to be I relaxed more there as a teenager than with my mother who could really have issues.
I am not saying there is not issue with being a stepchild. However, there are also positives. my children call my stepdad for grandad as he earned that title. He took on a woman with 3 children and he has treated them well and calls our children his grandchildren.
Do I have negative experiences absolutely... Stepmother 1 was not ready for taking on a man with children she was still to guilt ridden by leaving her child with her x. As an adult I understand this. As a child I felt she was the devil at lot of the time.
However for me stepmother 2 and stepdad were loving welcoming people I am pleased I had in my life. Stepmother 3 arrived when I was almost 30 and she was a kind lady to my children and my niece. She made my father happy.. It was good.
Its way moreabout how the adults manage it than it is about the step child. and sadly that can be complicated
