Who's who (the second time)

After Jillian was born, I dressed her in the same dress that Annabelle wore when she was a baby and wrote a blog entry showing a picture of both girls in the same outfit around the same age and asked, "Who's who?". Now that I have another girl, I'll do the same thing with all three of them. So, I'll ask again, which baby is Annabelle, which is Jillian, and which is Sarah (an no, of course they're not in order oldest to youngest)?
