DS (20m) hates having his hair washed atm. He was absolutely fine up until a few weeks ago (would lay back to have it done, hence no splashes in eyes etc). Now is wriggling, screaming, getting water and shampoo everywhere including eyes and of course, making it all worse. I realise this is probably a common phase and he will no doubt grow out of it, but does anyone have any tips for making bathtime and hair wash time enjoyable again ?
