I'd be really grateful for some advice from experienced parents.
DS is 16 months. When he's doing something he shouldn't, we tell him 'no', move him, and distract him. I can't say the 'no' is having much effect but we're hoping he'll associate it with forbidden activities at some point.
DH and I are fine with this, as our house is fully childproofed so there's not actually much for us to say 'no' to. However, I am having increasing problems with my mother, who thinks he should have learnt to obey 'no' by now. This is causing issues whenever we go to visit her, as he constantly wants to touch things he shouldn't.
Please tell me: at what age should my son have learnt to obey a 'no'? (With reference to touching plants, shelves of books etc). I was thinking perhaps when he's started talking and we can actually communicate? But maybe I'm being a bit PFB and am too soft?
