It’s not too late, but definitely start now. Ask for books for her birthday/ Christmas, get them from charity shops and join the library if you can - they also often do story times you could check out as she gets older.
Theres some good accounts on Instagram of speech therapists etc - peachy speech is one, I’ll try and remember some others. They often have book recommendations and give tips for how to read/ engage with books if you’re not too confident. Think bbc tiny happy people is quite good for this too.
From memory, the ‘that’s not my …’ books were really popular with my DD around that age, as well as the ‘where’s mr duck’ (dog, lion, rabbit etc - there’s a whole range of them) ones with felt flaps. Just reading it with different voices is great, or sometimes you can just talk about the pictures, try and encourage your daughter to turn the pages or point to the things she finds interesting, name what she sees etc. Also a good tip is to, at least sometimes, sit facing her with the book in between you so she can see your face, expression and how your mouth is moving etc. When there’s a book she gets really familiar with you can try stopping before the end of a sentence and seeing if she’ll fill in the blank.
Try and have books around that are accessible for her so she can choose to look independently or might bring one to you to get you to read it.
It honestly really is one of the best things you can do to help support her development.
