Keeping litters apart is normal and expected until first vaccinations but it shouldn't affect socialisation. With having different aged litters at the same time it is actually better that the younger litter are seperate as, being smaller than average they will be particularly vulnerable. She does look better but still smaller than average but, having just raised Evie's litter who were all smaller than average this isn't necessarily a bad thing. Small or not, she's definitely a little sweetheart and when you get her home she will blossom.
You must have lots of fun at the breeders home... Sooo many beautiful ragdolls to look at and play with... Your ragdoll kitten is cute, hopefully he will put on some decent weight soon... Good luck in the waiting game...

Thanks everyone, I will still visit at least once more before I pick her up. Just to see how things are going. I want to make sure they're socialized. The area the kittens were in wasn't real huge, not much room to run around. I know it's because they're so tiny now and eventually they'll move into that other room.
Also do the "mom" cats usually thin out during the nursing period? Because it seemed her females were thin but the males were huge??? I questioned her on it and she said while they're nursing it takes a toll on them & once they're not nursing they plump up again.
My kitty seemed fine, she did squeek once while I was holding her, so I let her down. It was hard to take her picture, she was all over the place!
Well anyways, I'm going to go back in a few weeks, maybe when they're 9 weeks old.
I guess I'm just worrying about every little thing now, my husband thinks I'm nuts!
All moms are different. Some do get a little thin while nursing and others maintain their weight well. My girls tend to get thinner when in a raging heat than when nursing babies. I think when nursing they spend a lot of time lying around with their babes, and tend to eat more vs. roaming around, calling a lot, eating less because their hormones are taking over when in heat.
It's natural to be worried, but maybe you need to take some breathers and reassure yourself.... you're doing the best you can. You have heaps of experienced breeders on this forum here to help you, and you obviously care a lot about the health and wellbeing of your new baby. Don't be so hard on yourself, worrying is a way you're showing that you love and care for her.

Now try to set some of that worry aside and enjoy the fact that you will have this sweet girl home with you and you are going to be a great kitten mommy
