Moderators: I would request the moderators to please split this post in OP’s topic in the BC forum as maybe she is struggling to create a new topic.
For your daughter: You need to register her as a BC via the MN1 route. FYI only follow the topic as follows:
british-citizenship/british-registratio ... 06886.html
The above topic has detailed discussion regarding this route and will help you in almost all your questions as your situation is similar to @cristina88.
(Note your child does not need any home country passport or visa to register as BC - UK birth certificate and your ILR BRP is enough).
Note: If you have any further questions, please keep in your OWN topic in the BC forum. I am sure this post will be split in your own topic in the BC forum soon and you can carry on in topic with any of your follow up questions you may have.
Good luck.
