2yo has become terrified of getting his hair washed

It makes me sad, he used to love it. When he was able to sit up in the bath I started asking him to look up so I could rinse, but he is perfectly incapable of sitting still. Water would get all over his face and make him gasp/panic/feel like he was drowning.Now he's fully mobile and it's like trying to wash a cat. He refuses to look up or sit still so I can rinse, so if I want to wash his hair it means a lot of screaming, soapy eyes, and panic.Aside from pinning him down, how do I cut down on the bath time drama? Is there any way to un- traumatize him? It feels terrible :( via /r/Parenting http://ift.tt/2eJbWV7
