Hi; well I'm sure there are much better brands out there, but I use Pet Head tearless shampoo and Pet Head Creme rinse conditioner for Chloe. The shampoo is good, has a night light scent and makes a great lather. The conditioner is great, makes her hair really soft, and smells so sweet.
They're each about $15 at Pet Smart/Petco or Pet Supermarket.
Hope this helps!, good luck in finding the best product for your baby! ^_^
