In the past week or so, Theo has learned almost all the letters in the alphabet. He can sign and say them - except for a couple like H and J. He’s just enthralled by letters - he sees them everywhere and tells us what they are.
Today he was on the swings and he made me stop swinging him so he could point out all the letters in "Made in U.S.A." which was printed on the inside of the swing!
