My three year old son is horrible and I just feel like I’ve totally messed up. There are moments of such a sweet kid but largely he’s really unkind, speaks to me like absolute shit, cries and screams and tantrums about everything, demands everything, hurts you when he doesn’t get his way, he’ll even deliberately piss himself to get what he wants. Some of this may sound like autistic traits but he stops if he gets his way which is one of the biggest things that makes me think I’ve just totally failed. We don’t give in but if you speak in a way he thinks you are he stops until he realises and then starts again. Just tonight he kept taking his seatbelt off his car seat and climbing out, so I had to keep pulling off and just sitting there because we couldn’t drive off as he would not get back in his seat. Screaming at us to shut up, go away, don’t touch him and take him back to the shop and buy him chocolate. The whole reason the tantrum started. We sat there for 40 mins at one point while he just went on and on with the screaming. My husband got out and put him on the pavement and said fine if you won’t put your seatbelt on you can stay here, he then pissed himself while looking my husband in the eyes saying shut up daddy. It wasn’t an accident, he does it during tantrums, I know it’s weird. We ignored it months ago and it stopped but the last two weeks he’s been especially difficult and started again. It got ridiculous to the point we’d Been trying to make a 20 minute car journey for 2 hours. I ended up having to hold his seatbelt closed while my husband drove and he scratched my hands so much they are ripped to shreds. It’s just not normal, he has so much power over us and I feel genuinely scared of his reactions. We obviously don’t let him be the boss but it’s just hell. That's the third day in a row we've been stuck in the car for hours due to him refusing to stay in his seat. I’m heavily pregnant and just think I shouldn’t be after we’ve fucked up so much with him. I'm having another little boy and I'm so worried this one will be angry and aggressive too. I don't know what I've done so wrong but I've massively failed at parenting. I don't know how people do it.
