Apparently we are not strict enough with him and he doesn't understand the word no because we don't say it to him!
Basically, we have chosen to only say no to him if he is doing something dangerous or something that we REALLY don't want him to do...and as our house is fairly child-friendly, there is no reason to say it very often. And on the occasions we do, he laughs and carries on so we use distraction rather than no as it works so much better.
Anyway, was at my sister's house today and he was pulling baubles of the tree (as he does at ours - but surely that is normal behaviour for a 17 month old??) and my sister and my mum both said 'no' to him and he just ignored them.
Am I making a huge mistake/rod for my own back or is my mum just being an interfering caring grandma?
