Delays?

There are quite a few things with my LG I feel aren't quite as advanced as some of her peers. She is still very much a baby in my eyes so I havent pushed things. Ie. She still breastfeeds, bed shares, and isn't potty trained (she is just at the point of starting to say when she needs a nappy change). In many ways she is very advanced! She can say the whole alphabet, count to 20, sings lots of songs, motor skills are perfect etc. But I worry that I am making her slow because I still see her as a baby. Also she doesn't go to nursery and doesn't have a father figure in her life so its just us. Probably another reason I am protective and not overly pushy with her
