A 'rude' mother-in-law has been slammed for insisting her grandson calls her 'mum' - in an attempt to 'one up' the child's mother. The unusual request came to light after the baby's mum took to social media to complain about a different spat.
In a post to Mumsnet, she said she was left upset by her family's behaviour at her son's first birthday party.
As the group prepared to present the youngster with his cake, her hubby's mum placed herself at the child's side. "I asked if we could swap so that both his parents are around him for the picture.

"I felt a bit weird with his dad and grandma sitting around him and me being further away," she added. But her in-laws suggested she was rude, claiming her request 'was uncalled for'.
Whether or not that is the case, worried commenters soon suggested the mum had another cause for concern. It transpired the birthday argument was not the first time the parent was upset by her mother-in-law.
The parent's post explained: "She has forms of trying to one up me around my son, including wanting my son to call her 'mum', taking a family picture when he was first born with her in the middle and him sitting on her with the rest of the family around."
In a comment, she also revealed her in-law's previous attempts to make parental decisions. "She wanted to pick his name, his school, pick him up from school every other day (she planned ahead lol), be the one to take him to the park every day, etc... and she would emotionally blackmail me when I'd say no," the mum claimed.
Stunned, commenters were quick to offer advice. Reverencing the party incident, one said: "In a vacuum I don't think this is that big a deal, but it sounds like she has form for inappropriate and overbearing behaviour which might make it more of a red flag." Someone else wrote: "She wants your son to call her mum? That's weird."
And a third replied: I don't think you were rude as such but you clearly feel pushed out by your mother-in-law. Take steps to make yourself feel more secure in your role as mum- you ARE his mum and no one can change that."
