About two years ago, when I was barely pregnant with our baby girl, my oldest daughter and I started a ritual. Founded on the desire to hold our bond, to be sure that we had special time together, our "Girl Baths" began.
We went to our favorite herb store.. here, and filled our basket with fine bath items, bubble bath, facial masks, foot scrub, and lavender shampoo.

The little one began asking last night to join our bath, and after we had some quiet time, we let her in. She repeatedly requsted water be ceremoniously poured over her back and shoulders, and even received the final touch of a spritz of uplifting rose water to close the space.
I hope this ritual lasts forever (although we might need a bigger tub soon :-) But even if it doesn't, the memories and connection will surely outlast a lifetime.
