If you start counting more, then she will too. Count everything, snaps on pjs, steps you go up or down, etc. We like to play 1 2 3 Weee (lift them up between two people as you are walking)- we altered this a bit and my dd counted 1 2 3 (lift), we counted 4 5 6 (lift), 7 8 9 (lift), etc. This got into counting higher and also multiples of 3 - which they are way too young to really understand, but it did help her later when learning to add and count by 2's, 5's, etc. We often switched up the number in which we lifted to see if she got a pattern. She often could.
Just go for it, count spots on a ladybug in a book, read counting books, etc. But, main thing is to have fun and make sure it is fun for her.
Do similar things with the alphabet. Look for things around you that start with a letter and name them for her and then challenge her to see if she can find something. And read, read, read.
