I have been a single parent to my child who is 5 this year since her father and I separated when she was 4 months old. As such he is totally absent from her life but she sees his family regularly, he just doesn’t bother. One of the issues we had was surrounding boundaries of parenting and being on the same page as to what was best for my daughter. When my daughter was about 2.5 we had one of them defining moments as a parent whereby I was out shopping with my daughter and she saw a giant peppa pig teddy she wanted. This teddy at the time cost over £50 and I couldn’t afford it ( her father incidentally doesn’t pay maintenance ). My daughter through an epic tantrum ( we’ve all been there) and I mean epic! I stood firm and after 40 minutes was able to leave the shop with her in some tact. I felt it was important I didn’t cave and buy her the teddy because of the tantrum and teaching her tantrums don’t get what you want. Later that evening I was speaking to her father, told him the days events and instead of agreeing with me he said he would buy the teddy, totally missing the point of what had been achieved that day. I wouldn’t let him undermine my parenting and give her the teddy I firmly believe discipline is an area where both parents need to be consistent. Shortly after he lost contact with my daughter and myself for various other reasons not related to this post. My daughter regularly sees her paternal grandparents and sleeps over. I am upset as today when I’ve collected her she has this giant peppa pig teddy which has been kept and given to her. I know it’s been some years since the tantrum / teddy event. But it’s the principle attached to it and the fact her grandparents knew the row we had at the time about him undermining my parenting and buying the teddy when as a single parent I can’t afford big treats all the time. His parents regularly undermine me but I often let it go, this feels different to me because of the background. Am I wrong to be upset. Honestly however harsh is appreciated. Thanks
