Not sure if anyone watches Dragons Den but ages ago they had this product on it 
Tangle Teezer
We saw it and I really liked the idea so we ordered one.  We used to have tears and screaming every single time we brushed Charlottes hair- morning and night. Its not too think but it has curls and when its out it gets so knotty- it was just awful.  This thing is BRILLIANT!  She never cries now- its just made something that was an awful experience every day, such a breeze.   I was sceptical but if any of your kids get really knotty hair and its a battle to brush then this is definitely definitely worth trying- I know it works out quite expensive but I would honestly pay it 10 times over, it works so well.  I got a couple for DHs nieces and they love them! They've just asked me to get them a couple more- I've also ordered one for myself and another for Kate on the off chance she eventually grows hair!
You can get them sent to NZ- and with the NZ$ being so strong its the best time to buy 
 and no I don't get commission! I just wanted to pass it on because its helped us so much!
