My ds has started biting. It's not a really regular occurance. Probably about 3 times in 2 ish months but as you can imagine it hurts and I want to nip it in the bud before it becomes too much...... I've just been saying NO in a really firm voice and taking him down from my lap/the sofa etc when he does it but he laughs at me (little sod) so I don't think he's taking it all that seriously.... Like I said he's nearly 15 months so I feel rather limited on the discipline side of things..... Does anyone have any suggestions or do I just carry on with what I'm doing?
