Bath time blues?

Something funny: Emma went from being fine with water and swimming pools to needing to take a shower with me being held ONLY. Seriously, this girl would scream like she was being murdered if you tried to put her in a tub for a bath even if you tried to be in the bath with her. On Thursday something changed and I have no idea why. I decided to take a bath to help my cold and Emma became fascinated with the tub and water until she insisted on coming in. She even tried to climb into the tub on her own. After she was in she had a splashin good time and cried when I took her out. Strange. What made her go from hating baths with a passion to suddenly loving the splishy splash of the tub?
