I am a 10 year nit veteran from when my DS1 was 4. Initially if I got "the letter" or found anything that could possibly be one of the little critters, I did everything required and eliminated every single nit from DS1's head.
Over the past 10 years I have spent hours with the comb and conditioner/spray etc in a battle with DS2 (11) and had some nit free periods.
With DD1 (9) it seems there is no way to get on top of it, 100s of nits every time which sometimes go down to a few, but quickly bounce back - it is just circular process. Now I have moved to a once a week comb - specifically an act of containment rather than hope for eradication - with the thought I have just 2 more years in primary school and then it will be over!
Does anyone else have this approach?!
NB just interested in what other people think - not looking for nit treatment suggestions - hair spray, combing, conditioner, tea tree oil etc etc - as I am aware of them all!
