I have been teaching my 2 year old words and Math on A4 size paper. I printed two words on each sheet and cut it in the middle. Can I use these sheets for showing my 3 month old too? My dots are also on A4 paper. Can I show them too? or should I make a new set for him with 3 inches word size and 11X11 poster boards for dot’s ? My dots are in red color. I think he is able to see colors now. But my words are in Black and white.
At 3 months, then ideally, the bigger the better, so eg., for the words, you could print each out on one full side of A4 instead of printing 2 and cutting them into A5 sizes. However, if it’s too much trouble, I think the sizes you are using now would be ok. The colors you chose are fine too.
