aww bless, i think i remember the terrible 2's! my daughter wasnt to bad just touching everything and wanting everything lol
all kids are different, my daughter is 7 now and if she is cheeky or answers me back, i make a point to say,
its not nice to talk to mummy like that , we arent friends anymore, and then ill be really silent, she hates it!! and she apologises instantly, sounds cruel but she isnt naughty that often and if i need to get her to bed and she plays up she gets cheeky and it works every time, she hates the thought of me falling out with her.
then when she does apologise, i just say to her its not nice to speak like like that coz it can upet people, and we have a big kiss and cuddle,
maybe try the silent treatment, kids DONT like being ignored and they need to learn that them doing these things can be upsetting and kids really dont like it when they upset you.
