i know were your coming from my 11 & 13 year old just wanna kill each other my 3 year old is going through the swearing stage my 1 year is so cute but she has such a temper my 15 & 17 year old step children seem to lie to us about things and then seems to go back and tell there mum what gos on here then the other day i was raising my voice at the 11 & 13 year old just at the front door and then i hear the next door neighbour "hey honey come and listen to this" i was wasnt swearing or abusing them i just was raising my voice, my kids just looked at me and then i said comeon inside we have big ears around then my kids thought that was funny . i agree it is sooo hard being a parent but with more then one it is really hard and trying sometimes but it is all worth it and i wouldnt change it for the world it more other people that annoy me more they forget they have had kids (but i forget there all the perfect parents just ask them)
