As a general rule, female and male bonds tend to be the easiest, however I have read of many female, female mother and baby bonds that work out well. That being said, either a male or female baby has the potential to not bond with your current rabbit, mother/kit bonds are not automatic. They are all snuggly now, but all rabbit kits are. When they start to mature they start to develop their adult personalities, so may not end up getting along with your female. It’s usually advised to separate the kit from mum before reaching puberty to avoid any potential fighting. You can keep them in cages next to each other so that they are still acquainted with one another but it can prevent any unfortunate incidents. Separation is recommended until 1 month after both have been spayed/neutered to allow time for the hormones to leave their systems. Then you can start bonding by introducing them in a neutral area.
If you keep a male kit, you will definitely need to separate before neutering and bonding, it’s also recommended with a female kit as mentioned, but I have known people who have simply kept a female kit with the mother and had them spayed when it was time and haven’t had any problems. However you do need to be prepared that things don’t always go smoothly.
