I'm quite new to mumsnet and have never posted a message before, but I am so frustrated today and feeling like a really bad mum. My dd is 2 1/2 and she's driving me mad. Up until recently I thought I was doing a fairly good parenting job..she was well behaved and polite, and lovely to be with. Recently though, she has become stroppy and whiney. She is fiercely independent, and won't let me help her with anything..this often results in her getting frustrated and having a tantrum. She won't let me cuddle her much and always seems cross with me. Where am I going wrong?
