Bathtime Tears

My 3 month old has been Sicky. As part of her night time routine we take a bath. From day 1 she has Loved baths!!!!!! She is Colic and on special stinky formula and needs a bath everyday. For some reason the past 4 nights she has hated the bath. No smiles and after 2 min max she is screaming. Yesterday, I took a shower with her and she seemed to enjoy it so I was hoping tonight bath time would be good again! Nope!!! As soon as I put the warm washcloth on her tummy she screamed! I know it's not to warm there is nothing poking or hurting her back. I am so sad she hates it now!
