I have washed Lexi twice already, once at 9 weeks, then again yesterday!
She isn't keen on the washing part, she just stands there looking miserable.
But I've discovered she LOVES being blown by the hair dryer!!
She goes crazy :lol:
I got Lina at 3 months, so I can't be much help on the age thing. However, I do use baby shampoo to bathe her. It doesn't hurt her eyes and it smells good (it doesn't last forever but it still smells good). You can use pretty much any kind, I perfer Johnson and Johnson..that's what I used on Gaige when he was a baby too lol. There's this kind that smells like Lavender...it's my favorite.
