We finally got our son to wash his hair. We used our 2 month olds MAGIC shampoo. I gave the baby a bath as our older son watched. Then my husband took him into the shower with an empty bottle they put water in it and our son poured it onto his head, soon our son was asking for the magic shampoo. he was soooooo excited He told me how he looked up so the water went down his back. We made a big deal about it. He wants to wash his hair every night now we are so proud of our little man. Thank you every one for all of your advice.
