DS is 3 and is VERY resistant to having his hair washed. I remember not liking it when I was little but this seems ridiculous. He has a massive meltdown EVERY time, it's awful. DP usually does bath time while I feed baby DD but he is away at the end of the month for a while and I am dreading doing it myself. At the very least I think DD will get upset by it and then I will have two of them shouting at me 
Any tips on how to improve things? We have tried getting him to lie back so the water isn't being poured over him but he won't do that. He used to manage with a cloth over his eyes but now apparently nothing will help. I am tempted to try one of the jugs with a flexible rubbery front but I don't know if he'll even let me near him with it!
