Not really sure how to tackle this situation so looking for some advice. Husband has a daughter from a previous relationship who is a very lovely well behaved girl, however on the rare occasion she is naughty he won’t tell her off or does it really half heartedly. A couple of weeks ago she punched ds and he didn’t address it at all. In contrast, he gets really cross and shouts a lot at ds who is (4 years younger) for what I would consider quite minor things such as getting up from the table when he’s supposed to be eating his dinner. I’ve spoken to him about this and he agrees he does do this but then doesn’t change his approach. I like to think it’s because he’s more comfortable with ds because he sees more of him rather than because of any kind of preference but I’m not really sure what to do now, just ignore it and hope it doesn’t foster resentment between stepdaughter and ds who generally get on very well or if there is something else I can do?
