Dc 4 and 6. 18 months apart. Boys. They do a nicely sometimes but every day, sometimes every hour, or more,they're squabbling.
Eldest annoys youngest. Grabs him,wants the toy he's picked up just because he's picked it up. Snatches, hangs onto him,pulls clothes. Abd so on.
Youngest - reacts, in general. Pinches, hits, kicks, stamps. This sounds really bad, but he ONLY does it when his brother winds him up.
Eldest then cries.
This is not all, and sometimes it's the other way round. Some days I barely leave the room (go to the loo/make food/take a call) before one is screaming.
I just don't know how to deal with this. I tell youngest off for scratching or whatever. He always says "but he did x,y,z". I tell oldest off for winding his brother up . I try to talk to them I ask if it was kind, ask why. Ask if he'd like the same doing. I praise good behaviour.
I have bought parenting books which are mostly unread because honest by the time they're in bed, I don't want to read them.
