Get a bath seat. I had a pic of DS in his to show my BB's here: https://www.bellybelly.com.au/forums...php?photo=9604
DS would splash and splash aswell.. think its just what they do lol. But least with the bath seat, they sit in it, you dont have to hold them, and you can avoid getting drenched!
You just get them at Bigw or kmart. Theres some even on ebay.
Got one of those, found mine at Target. When I was in the line waiting to pay for it I had a mum come up to me and say how great they were. I totally agree, they are a life saver. I can have both girls in the bath, bubs kicks away and I deal with Miss 3 (hairwashing etc) if need be.
