I am a British citizen and I got the citizenship through my mother where she has the citizenship by birth (born and lived in the UK for about 4 years); however, I didn’t go to the UK before and I got my citizenship as per the amendment for the Act 1981.
My question is if it is possible to apply for British citizenship for my wife and daughter? knowing that I got married and I got my daughter before becoming British citizen, and m daughter now is almost 15 months old (she is still a baby

Note: my daughter now has a British father and a British grandmother, wouldn’t that help to make the application process for British citizenship easier?
Thanks to all in advance
