Hithere
The father is as responsible as the mother in raising the children -not sure why some posters blame the uterus carrying person while giving a pass to the person with the penis
FFS Hithere, what a load of rubbish you are posting, not to mention complicating things.
Child has not been to the dentist in 12 months, I get the impression Gran asks Mother if she can call her private dentist to see if she can get an appointment, she could not, but she did what I would have done, she tried to find a solution and help out. I do it all the time, luckily my daughter is educated, and knows the difference between trying to help and interference.
Also bringing the Father into this is irrelevant.
