I am just wondering if anyone else has had this? I am due to have my first in 3 weeks, but my DP has a son aged 10. I am increasingly becoming annoyed at his lax approach to parenting the closer I get to sharing the parenting of my own child. His son just swore at the TV, shouting "dickhead" at the actions of the character. To which I quickly pointed out that we don't talk like that and we can think of better and less offensive terms. His dad laughed and asked who says stuff like that (as always, taking responsibility away from his son as it always has to be someone else's fault.) Although it annoys me a bit, ultimately this is his son. However, I can see a future with our daughter where I play 'bad cop' and daddy constantly undermines me if I have to stand for rules/ boundaries... This is, by the way, part of an overall approach to parenting in which he doesn't like to tell his son it is bedtime ( I do that), tell him he has to eat what he has chosen etc Basically, anything unpalatable or less than fun. I really don't want to spend my life being the parent who has to do all that while he gets to be 'fun parent'. Is it normal to be stressing about this at this stage?
