DS has a 9 year old step daughter and a 20 month old son and the other day he said he thinks I favour his son and treat them differently. I don't think I'm favouring him at all. In all fairness I've only known his step daughter for around 2 years and she's shy so when I first met her I didn't want to be too "full on" and make her uncomfortable. She's still quite quiet around me and I try to make her feel comfortable but I think DS was expecting us to have a close relationship straight away and that would be lovely but it's up to her. I probably do pay more attention to my grandson when I'm looking after them because he's so much younger. Sometimes her and my DD (who's 14) will go to the park or get some sweets from the shop together, according DS that's trying to get rid of her. He also brought up that I forgot her birthday not long after meeting her, no one had mentioned it to me so how could I have known? He seems to be over thinking things a lot and I'm not sure why
