Basically I asked DDs father to buy her some SHOES for pre-school, proper full shoes (colour doesn't matter at pre-school) XP bought Dd a pair of trainers, I thanked him for them, closed the front door and moaned at DP that he had bought trainers and that I'd have to swap them for shoes and make up the shortfall in price.
DP thinks I am being ungrateful and that I am lucky. I disagree, we get £61 a month from the CSA for dd, I thought the least he could do is buy her a pair of shoes for school, bearing in mind in 3 and a half years this will be the second pair of shoes he has bought her.
I don't think a father buying shoes is lucky I think it should be expected, especially since the maintenance we receive is so low. DP thinks this was nice of him. I also think that changing them from shoes isn't me being ungrateful, I said thank-you for them!
