Counting/reading numbers 1-10?

Anyone else’s lo counting and reading numbers? My daughter is 20 months old and about 2 weeks ago she started pointing at numbers and yelling what they are! She has been counting to 10 for about a month now, but it really shocked me when we were in a store and she saw a sign (aisle 2) and pointed to it and yelled “mama 2!!” And then did it for every aisle 1-10. We listen to a lot of counting songs so I figured that’s how she’s learned to count, but recognizing numbers?? Is it normal at this age?
