Daughter and step children don't get on

[Clementine25]

My teenage daughter (15) and her step sisters (11and 9) don't get on. Daughter does her own thing being a teenager but meal times are a nightmare! Icy silences and no interaction despite best efforts by me and partner! Suggestions on how to manage please! Or I will go and eat in the garden on my own!

no advice I'm sorry but sympathise, I hav a 15 yo dsd and 11 yo dsd, wen my dd was younger they got on really well, now always bickering and icy stares/ignoring.
dsd is here eow and her dad, my dp thinks my dd should b home that whole wknd and do stuff with dsd, my dd has started to resent he feels that way.
Iv kinda give up with it all

meant 15 yo dd
