Well I dont as such but I do find it difficult sometimes when DH is with DS and I see him do something I wouldnt. We had a chat about this the other day so DH knows all about how I feel and very graciously (even though I know it pisses him off sometimes) put it down to the fact that I am with DS all day etc etc...
Point is, I know and understand that I feel like this sometimes but dont know what to do about it.
Oh, and I think some of it is to do with those pesky risk assessments.
