To date, Ryo can count to 100 by ones and tens in English. Rocco can count to 30. Aida can count to 20. Ryo can count to 30 in Spanish (maybe more...need to check again). Rocco can count to 20 in Spanish. Aida counts to 10 in Spanish. In Japanese: Ryo - almost 20, but not always, Rocco and Aida up to 10. They count to 10 in Filipino...but that is because I can only count to 10 in Filipino...guess I need to learn more!
It is fun for me and for them! I am so amazed at how fast they learn!
