My ds is taken out for the afternoon quite regularly by his grandad (dp's father). Today we found out that he had been met by my partner's sister ( and her partner - called A ) while out. Am I being unreasonable about feeling slightly uncomfortable about this because neither I nor my partner were informed that this was happening even though my partner spoke to his father a couple of times through the afternoon. I should say that there is a slightly strained relationship currently in any case between us and my partner's sister ( plus partner A ) due to A's difficult manner, i.e totally patronising know it all; and they have asked in the past whether they could take out ds alone for an hour or two. We have declined because they do not know him very well. Well am I, or should that be, are we?
