just wondering what people think of this.....my 15 year old step-daughter intervening and telling my nearly 2 year old (her half-sister) that she will go in the hall if she carries on, she was wiping yoghurt on the tv! I said to leave it to me and my partner as we were both there at the time...my partner said the 15 year old was in there first and this is ok...he said this in front of me, so feel undermined....then he gets annoyed with me and thinks I'm wrong....I just think its parents job not hers. Don't mind her doing it a bit, like saying don't hit or whatever, but time out is last resort and up to us not a child!!!
