Brief background, dp and I have been together 3 years, we have ds almost 1, dsd 5, my Dd 5 and ds 8.
We get on well with dp ex everything is amicable.
Over the last year I have spent a lot of time caring for dsd along with my children. Often at ex's request but always with her knowledge. We have also spent a lot of time just me, dsd and baby so have become quite close.
Ex has had a baby very recently and for various reasons dsd has spent a lot of time either with us or Mil. I am aware that she may be feeling pushed out so have been making a special effort to make sure she feels loved, happy etc when she is with us.
Today dp was at Mils doing her garden and I was home with all 4 children. The girls were playing upstairs when dsd called down "mummy", I assumed it was part of her game with Dd so ignored it and she shouted again. "mummy, can we have a drink please?"
I just said ok and took them a drink. I know I should have corrected her but I don't want her to feel rejected here if she is already feeling pushed out at home.
How should I handle this...
