2 year old DS biting

[WutheringFrights]

How do I stop him!?
He is 2 tomorrow. I think that a lot of the biting is frustration because he can't make himself understood, he can only say a few words (which only I understand!)
The biting is getting worse and more frequent. Usually it is directed at his big sister, who is 4, and often when she is properly annoying him (I obviously have suggested to her she should stop), but that's no excuse to sink your teeth in!
I usually take him away from the situation saying no to him and telling him not to bite, but he grins and gnashes at me!
He has bitten me three times in the last 24 hours, once because I wouldn't read the same page of bear hunt again and again. Then when I told him off for biting me I turned around and he bit my bum! This morning he leaned into me for a cuddle and sank his teeth into my arm!
I just don't know how to stop him and I am really worried he is really going to hurt DD and scar her.
Please can anyone tell me what has worked with their vampire toddlers!!

I tend not to shout or raise voice in our house but when DC was biting I did.

We did: "OUCH. NO. You do NOT bite" with raised emphasis on the capitals. Not screaming at him, obvs, but raised voice. Then moved him to a safe but boring space & ignored for 2 mins. Completely. Then went over, reiterated calmly that we do not bite ever. Had cuddle, moved on.

DC hated being ignored (reasonably - I would too!) hence ignoring was very brief.

Took a week or so to work, and during that week if he was going in for a bite we said "We do NOT bite" - same words every time.

It's hard & I hated it (I'm shit at discipline...) but did work. When he didn't bite but reacted in a non violent way to bed g upset we praised & empathised massively OTT too (Oh my lovely boy, of course you must be upset because .... Well done for not biting. Let's have a play & cuddle ... Etc etc)

I was trying to attempt the ignoring thing when he sunk his teeth into my bum! Maybe I shouldn't turn my back on him

Ow!

It's a nightmare, and the second chomp in was why we had to physically move the vampire away! But - he hasn't bitten for well over 3 years now hurrah! There's an end in sight!
