I am the eldest of 4. Sister is married with kids same age as mine, brother married with a two year old but SiL has two from a previous relationship which was unhappy because of her ex’s controlling ways.
Her children are similar aged to mine and my sister’s. The boy’s behaviour is challenging to say the least especially if he is not the centre of attention. . My brother is just a big kid so plays with him all the time so I don’t think he realises what a problem this behaviour is.
The boy adores my father. One example is when brother visited, my father was out with the grandchildren. When he returned the boy had an absolute meltdown attacking my nephew.
My sister confessed that her husband ( he is not controlling or abusive in any way) said that his kids are no longer allowed to be in the same room as these children. Ironically this was because of an incident with the girl, who is very shy, hurting my niece.
So that’s the background.
Youngest brother is getting married in a couple of months. My niece is six and asked to be a flower girl ( not a brat but excited and her cousin and friend had been one) but future sister-in-law said the wedding was for ‘big people’. Upsetting as we would like a family wedding but not our wedding! It is totally up to them.
My sister did ask SiL to clarify that it was child free stressing that no more would be said etc. Well it turns out her nephews will be there and her cousin’s toddler/ Goddaughter was flower girl.
My brother is making it child free as he thinks our elder brother would bring his stepchildren and chaos would ensue.
Essentially our children can’t go to brother’s wedding as he refuses to confront our other brother over his stepson’s behaviour.
If this was your brother would you say anything?
