I wouldn't call it love so much as increased interest. Sister at least isn't a vegatable anymore and doesn't require all of moms attention. K does think that little T is very fun to push around in things (thank god for a strong baby gate on the stairs). She of course thinks everything that Taylor has is instantly what she needs. I feel this an absolute universal feeling amongst siblings. I must have they have even if I am very content.
From time to time, there is some interest like feeding T and helping scrub her in the tub. But no unsolicited affection or attention.
We don't have any fight yet either, so I know that will come. Little T can't move well, so K can get away but that will change
For now I will take what we get at 8 1/2 months.
