My 4 year old nephew was round this morning with MIL, bear in mind he is a very very spoilt child and isn't used to the word no, already has a very entitled attitude at 4 years old and he cant do no wrong his mum and nans eyes. DN demanded to go upstairs and DP said no because it's upside down right now and no one is up there (we're currently decorating DD room and all her furniture is on the landing and in our bedroom so it really is an absolute state up there right now). Anyway, DN carried on and on and on about going upstairs so MIL says to my DP can you just take him up as he doesn't believe you. DP still said no because of the above reasons but finally caved and went to take DN upstairs but he then demanded MIL goes with him too. So of course she goes upstairs with him aswell. I know it seems really petty but if we've said no then he should just accept it and MIL should've also backed us up on that too right? It's really bloody annoyed me.
