This is the way to go. Stairs counting And Steps counting are awesome way to make them fall in love with numbers. Also, while on a walk, tell them what is what like these are stairs, that is a donkey etc. despite they can utter it or not.
One more comes to my mind, tell the spelling while looking at the things like if there is ice cream written somewhere, say it like I C E C R E A M.
Kids just love spelling random things, it's like playing a video game for them. My kids have trouble sitting still when putting on their clothes, so I ask them what's on their shirt, what's on my shirt. You can start easy like colors, or animals. They recognise letters well too as long as the font isn't weird. My 13 month old can't talk yet, but he will point to letters if I ask him "Where's A?"
