It has been a long time since I have bought bubble bath. Last time I did Richard put the whole bottle in the first time we opened it. Well, I got some this week and the kids have had so much fun together! Richard wakes up every morning, brings me the bubbles and asks if he can have a bubble bath. Then he will stay in there for 20-30 minutes playing in the bubbles. Hannah lets him do whatever he wants to her in the tub; he puts bubbles on her, dumps water on her head, they splash on each other, etc. They have a lot of fun together.
