Hi, do you think Aveeno Natural Baby is an okay sunscreen to use? I know Aveeno used to be a good, clean product, but I have head they are no longer clean. I have some here and just wondering if it is safe to use on my 9 month baby. Also, does it have to be washed off at the end of the day? Today isn't bath day, but should I still wash her after using sun block?
