I hate confrontation of any sort, always have. I think i've inherited this wimpish gene from my lovely DF, who I have never seen get into an argument with anybody to this day. other than the occasional episode with DM but you can guess who wins the argument there
So now that DC (3) is growing up it's becoming increasingly clear to me I need to grow some balls/man up (God I hate these phrases), as there will be moments where my DC will need me to stand up for them. No major occasion has arisen yet and even though I am fiercely overprotective over them and would not let any harm come to them, I still really need to work on this wimpishness.
So today DC was playing in the back garden, he parked his bike quite close to the fence we share with one set of neighbours. (He wanted to stand on it and look as they had friends over hence lots of noise and laughter). I should point out we have only recently moved and he doesn't know the kids very well, has never played with them so was very curious. I was watching him from the open window whilst feeding baby. I noticed the group of kids come over to the fence to dc and start badgering him for his ball claiming its theirs. He remained silent but didn't give in. Then I saw one older boy climb up and grab dc's bike to which I shouted 'oi' and he sheepishly put it back. After a few more minutes of this badgering dc told them firmly no they cant have his ball, I then intervened, told them its dc's and brought him back inside for dinner. I felt so so proud of him for standing up for himself, because as a child I would have just handed it over. Some of these kids were much older around 7,8 but he wasnt intimidated by their behaviour.
As for me, I try not to let people walk all over me now in adulthood but thats only because I avoid those types of situations. If the children's mother demanded the ball saying it was theirs even though I knew full well it wasn't, and seemed like she's picking a fight I may have just given it anyway thinking its only a bloody ball and not worth falling out over.
I'm bloody pathetic aren't I 
So aibu to wish I could stop being like this? How can I learn to be more assertive before my dc learn to pick up on this weakness of mine?
