Kitten update, day... 6?

I haven't gotten to post updates this week because I've been sick, plus some absolutely unexpected shit went down at work, but I have nothing but good news about the little family.

Rosa responded well to my cues and figured out how to use the litter box within 48 hr. It's still a bit funny watching her go as she chose one of the kitten sized boxes as "hers", so when she tries to bury it, its with newspaper and blankets as well as litter. We haven't quite learnt communication yet - I feel like she wants something she's warbling for, but maybe it's just attention and pets - and she definitely gets a look of solid relief when I have all 4 kids romping on me, like oh ok you've got this imma nap.

The kittens are all eating on their own, though they're also still nursing. They think that Big Mom is Best Toy, who comes with variations like Chew Pants, Attack Toes, and Climb Up Back. They also doze off on me occasionally in those 5-10 min kitten power naps.

They're all curious about the door. I need a plan of attack.
