I feel your pain! I went through a phase where it litterally was all I said as well. Now I only spend half my time saying it! It does get easier, but like I said to another poster regarding another issue, sometimes you have to just chose your battles - is it really worth it? For those that are you really have to stick to your guns, for others you have to train yourself to think is it really that bad if she does xyz. But if you say no automatically you can't immediately go back on your word or you're not being consistent. Instead return to that issue later.
You can also try other words, and facial expressions just to keep your own head sane!
I use raised eyebrows, big wide eyes, the question 'do you want to make mummy angry", or the statement 'mummy is going to be sad if you do that', and 'what do you think, is that a good / right / safe thing to do'?" I use all in combination with putting her in the hall if she has really overstepped the mark, or taking toys away or television off again if the situation is bad enough to warrant it.
It all ties in together, but Indie has to know you are mum and mum is boss. You will stop saying 'no' as often, I know you probably don't believe me, but it does get better - promise
I try not to use the word no but instead say things like 'Evie stop' 'wait' 'what have you got?' etc
Also... i know all parents are different just like our children are different but i do try and say yes as much as i can. As long as Evie isnt doing anything that will hurt her or other people then I tend to be quite relaxed
