Eva doesn't like me...

The girls were in the bath tub (I know a lot of stories come from there!), I'd washed Eva's hair & it was Grace's turn. When I started washing Grace's hair, Eva started screeching, stepping on Grace to get between us. I couldn't believe it - she had to be jealous, she didn't want me semi-holding Grace... wanted me to hold her. When she did this Grace said, "Mommy! Eva doesn't like me..." it was so sweet & sad at the same time... she was so innocent, but it really hurt her feelings. I said, "No honey, Eva loves you she's just jealous." Not sure she totally understood but she seemed to think about it for a bit.
