Same as a few people already - if he was asleep I'd be ok, otherwise, DS would just have to come in with me and play on the floor of the shower. I started using Moo Goo products quite early on (DS was about 3 months old when I started), so I was never worried about him sucking on shampoo water or body wash - it's water grade! So, I'd recommend using natural products (not just products that claim to be 'natural', actually research it!) if you're showering with babies - ingestion of anything else can't be great for them!
