Well, since vanilla is basically a highlighter or lightening gene, that should help at least some in deciding if the babies carry vanilla.
From your pictures, I'm going to say the first baby is vanilla, the second is not, and the third is a maybe. The pastel gene will affect things, that is true, but I feel pretty confident the first baby is a vanilla spinner. Maybe a few more pictures of her ?
The second baby doesn't say vanilla to me at all. I'm going to call that one a pastel pinstripe.
The spider is obviously a spider and not a bumblebee, I am leaning towards it being a vanilla spider, but it might just be a really light spider. Any chance for pictures of the parents? I'd really like to see them, and see how their looks translate to the babies.
