Reading numerals

We all helped dad tidy up the lounge this morning, and then we got to play trains. I showed dad that James had a number 5 on his tender and pointed out the black coal and dad told me about how the trains used the coal to make steam. Later I found Henry and showed dad the number 3.
Dad asked me about Peter Sam and Toby and I correctly spotted the number on their sides was a 4 and a 7 respectively. Dad thinks me recognising numerals, up to at least 7, before I'm even four is pretty brilliant.
I've been really interested in numbers and counting the last few months, and I regularly count things and spot numbers and letters. I've been spotting the letter B around town since Christmas. When I start counting things dad often joins in and we count together. Today I told dad I was three and would be four at my next birthday, and five after I'm four. So we counted everyone's birthdays in Maori and English.
