Most rabbits don’t like being picked up, so most of us avoid it so that we can have a good bond with them. It’s important to be able to pick your bun up in an emergency, but it’s not a good way to bond with them.

Like you’ve been doing, lie on the floor with her, and give her treats/pets. You can even try not touching her at first, so she gets used to your presence.

Most bunnies don’t like being picked up and held, it’s just in their nature. If she doesn’t like it now, as a baby, she’ll like it even less when she’s older. Some bunnies don’t enjoy being pet either, at least not for a while. It took Asriel months and months of ignoring him and just having him sit near me for him to feel comfortable with pets, and even now two years later he’s still a bit iffy on pets The important thing is to not rush it. Let them do their thing on their terms. If she doesn’t want a pet, don’t force it. Before you go in for a pet, you can see if she’ll allow it. You do this by offering your hand, palm down, and if she lowers her head you can give her a little pet. Do it in small increments though, like 10 seconds each time so she’s not overwhelmed. Also remember, 1.5-2 months is still new for her and no time at all. She’s still probably adjusting. It can take some buns 6 months to a year or more to open up to their hooms
