My 3 year old is going through a phase of not saying hello or goodbye to my mum, when she goes there twice a week. She can be affectionate towards her nan in other ways (and apparently more so when I'm not there), but often she'll refuse to say goodbye/hug/kiss and ask to go home. Whilst my mum doesn't make a fuss, I can tell it upsets her. Her other nan (my MIL) looks after her much less often and my daughter will always give her a cuddle and kiss goodbye, and I'm worried she's showing her to be the favourite grandparent. I wonder if it's because my MIL does more fun things with her than my mum does.
I know I shouldn't force anything or let this get to me, but it's on my mind at the moment a lot.
Appreciate any advice. Is there something different I should be doing?
