We went to the supermarket today and as has happened for the last two or three weeks, DS1 (3.6yrs) clamoured for a toy, and DH wanted to give in to him just for a quiet life. I made it clear as I have done every time this has happened that I don't want to DS1 to get a toy just for being at the supermarket (it's a necessary but boring part of family life, and DS1 just needs to get used to it) so DH told DS1 that he wanted to buy him one, but I wouldn't let him.
I was furious at DH using me as an excuse to do what he should have been doing in the first place (saying no). This happened this morning and I am still so cross - mainly because DH doesn't see that he did anything wrong.
