New bedtime routine take 2

So last night was a little off because Camille doesn't get done with her swim lessons till 7pm! I made Bea dinner, cleaned up the kitchen, ate dinner myself and was trying to get her in the bath when Izak and Millie walked in. I finally got Bea into the bath and let her have a bit of play time. When I came back into the bathroom she'd squirted the entire floor, bathroom door and hallway with water - all from her position in the tub! I was very disappointed and told her so. She knows better. She then brushed her teeth and went to bed without the piece of chocolate that I had promised her earlier. She cried, but then fell asleep shortly after. Millie was up again as usual and finally fell asleep around 9?? But when I woke up this morning they were both in my bed!
