Bath time in the BIG tub

In our master bathroom we have a small shower and a huge tub. It is not a jacuzzi tub but it is big. Will wanted Elsie to try it out one night for bath time. She liked it ok but ever since then Will asks her if she wants the little tub or the big tub and she always chooses the little one. We think it might have something to do it with all the bubbles!!!
