Apologies in advance if I am being ridiculous. I have one DS who is 11 months. Over the last few days he has been pretty horrible to be around - hitting, pinching, biting, hair pulling etc. He's particularly bad when getting his nappy changed or teeth cleaned but it can happen at any time really.
Is 11 months just too young to even think about discipline? Should this just be accepted as a stage that will pass or do I need to take some action now? I have no clue how much he understands. I try to look him in the eye and just calmly and firmly say no but I have come pretty close to losing my temper and shouting. Plus the more I say no the more he seems to think it's a game and does it again and again.
He has just finished his first full week at nursery but I am not sure if the two are connected. He seems to have enjoyed it so far and settled well.
When is the right time to start being consistent about discipline?
Thanks.
