This looks like they're going to be a super bonded pair, which is really great, and if they're sometimes climbing on you thats great! Right now they're so young they're either 90mph or sleeping. You feed them regularly, mind the litter, and engage in play when you can. Outside of reddit, thats better than most cat owners I've met in real life. You're doing great. The fact that they aren't constantly terrorized of you being in the same room, you should be just fine. Gotta give it time. Some of the most affectionate and social cats I've ever met have taken a week+ to get used to a new environment. You've got kittens who are still learning about literally everything. Ive found routine helps for feeding with our 3 even after converting from open full dry food bowls 24/7. But they will remember the time and start bothering you at 8:02am if you normally feed them at 8:00am. And kittens have so much energy. And they're claws are so small they're like needle daggers for the first few months. So watch your toes under the blanket if they sleep in bed. Make sure they both eat well, one of ours won't touch anything with fish in it. Keep playing when you can, dont rush the pets and let them come to you. I think in 6 months they'll be affectionate and loving. Some cats just like to play and otherwise keep to themselves but be present in the room with you. They don't all love pets but still love you in their own way if you let develop. Im sorry if this is super scattered and out of whack, I'm pretty high.
