How much baby wash and lotion to buy?

Ashley

I'm buying the baby shampoo/wash and lotion online and want to avoid paying shipping a bunch but also dont want to buy too much.

The shampoo/body wash is 8oz bottles and the lotion is 9oz. They also have a 32 oz refill shampoo/wash.

Just curious what other moms went through in the first 6 or 12 months. Thanks!
