I don't have 3dc but some conflict between siblings is normal surely?? I mean living in close quarters with anybody is annoying, when you're both immature (ie, children) then it's going to come to blows occasionally.
I don't think the presence of a third will make any difference, apart from giving them someone else to fall out with/gang up on!
I wouldn't have a third to resolve conflicts between children. It won't. Siblings always bicker but watching our kids is wonderful. I would say the benefits for them far outweigh the bickering, however irritating.
Have a third because you want a third child. Having 3 is brilliant. Hard work but well worth it. Extra car, bedroom, etc requirements etc and all.
No it definitely did not resolve conflicts in our case. Dd1 and Dd2 were 6 and 3 when ds came along. He is a total cutie rampant tear away who pulls our house asunder and draws on anything that does not move out of his way and I wouldn't have it any other way.
Conflict and rivalry is normal! You just need to watch if it is healthy or not. (I have siblings). Sometimes it is hard to watch but I remember being the same with my brother as my two are. One minute hating, another fighting.
The main thing as parents are to not take sides and help them resolve conflicts. Oh and be a common enemy.
I'm one of 3 and there was bickering and rivalry between all 3 of us at times. It just means more possible combinations when it comes to siblings falling out or ganging up against each other. It certainly didn't mean that the oldest 2 out of 3 of us were magically friends all the time.
I don't think there's an answer to that, it depends on the individual children. It's early days for me (4yo, 2yo and 6mo). It certainly hasn't stopped the older two fighting but it is lovely to see them start having a relationship with the baby.
