When Molly was about 5 to 6 months old and transitioned to the big tub we deemed bath time Daddy's activity. It gave him a chance to do something with her that was their time. Occasionally I have to fill in but most nights Molly and Dad enjoy splashing and washing away in the bath before bed. Its so fun to hear the giggles and laughs that come from the bath room while I prepare her bottle and pjs.
Clean little piggy!
