I bathe my little ones every 7-10 days in the winter (depending on how cold it is) and every week in the summer. In the winter I blow dry their hair and in the summer I let them air dry
I have to alternate shampoo and conditioner every 3 moths or so because I have a feeling that they are just like me and get itchy with the same shampoo if used too long.
The vet said to bathe them every 1 or 2 months because their skin gets dry. I tried it once for about 3 weeks and, oh no, they didn't like it and neither did I (they got itchy anyway).
I believe that they feel better when they're clean, because Nini walks with a little more flair in her step and Nicky...well he's a boy and is happy being nice and filthy, but when he's clean, mommy can't get enough of him and he likes that
The nails...I don't dare, yet
