Back story: I'm one of the middle children of 4 siblings. Have left the family home for over 6 years and have had 3 DC's of my own since.
I've had to move back to my parents for a few months whilst renovating my home. During this time I have noticed that my mum treats me differently to my other siblings and even my DC differently to her other grandchildren. I get that every parent-child relationship will be slightly different however I can clearly see that she favours the sibling directly older than I and the sibling younger than me more than me and oldest sibling. I can also see she clearly dislikes my middle DC and purposely antagonizes them. (I've pulled her up on it and that behaviour has stopped). Anyway is this normal behaviour? If you have adult DCs and/or grandchildren do you treat them all equally or do you have definite favourites?
