Carmen, please please remember that you're still dealing with a little baby, and you have to set your expectations about 'behaviour' accordingly. Unlike adults, babies & toddlers don't have impulse control, from memory it takes a good couple of years before this skill gets mapped in their brains, so you have to be consistent with your rules, but kind in how you implement them, and rely a lot on removal & distraction - ie tell/explain her your rule, but then pick her up & remove her from the situation. THe other thing with kids is that they tend not to hear the "Don't" in the phrase - as in Don't touch the TV Remote", instead what they hear is "Touch the TV remote". so if you can, try to rephrase the request into a positive request like "please leave the TV remote alone". This is also a good way to minimise the number of times you use the word no, although it's much harder work, because you have to think about what you're saying so much more, as it's not as easy as just saying no. And like Sarah said, Praise, praise praise - kids just want to make you happy, and if you notice the good things that they do then these are the activities that they'll repeat. Also, your DD is probably reaching the age where she realises just how much there is to do in the world & how physically limited she is (due to her size & limited co-ordination), and this is frustating - she just wants to get out & learn about everything.

Have a little faith in yourself - if you've got good manners then there is a very good chance that your DD will do just fine, because you are her biggest role model. And, it's cliche, but don't sweat the small stuff - she's probably only putting her feet on the table because it feels interesting, she won't be doing it when she's 4. I think that if it's not hurting them, you or the thing, then go with the flow a bit, otherwise it will do your head in, and you'll be stressed & she'll be stressed and then you'll just have a vicious circle of stressedness.
