My 2 year old is boisterous and I redirect where I can and save the word no for when I really mean it. This generally means she listens and stops when she hears it. Her dad seems to have a phobia of saying no to her. The main things it's necessary to say it over are being too rough with the baby, being boisterous around the dog and hand holding near roads.
If she is being too rough with the baby, her dad will pick the baby up and move him away. If she's being boisterous around the dog he'll shut the dog away. If she goes to cross the road without a hand he'll either follow her or pick her up to stop her. He never addresses the issue of what she shouldn't be doing.
He thinks I'm expecting too much from her but she isn't far off being 3 and she mostly listens to me when I say no. I don't see how she'll ever learn to do the right thing (I.e. be gentle around the baby and dog) if we don't encourage her to do so and just keep protecting her from being in the situation. AIBU?
