I think it's an absolute blast to watch and listen to Cooper learn new words. Last night he learned to say "Amen". After we say his prayers, we of course say, "In Jesus' name we pray, Amen". Amen is the only part of the prayer he knows so far, so as soon as Mommy gets to that line, he jumps the gun and starts saying over and over "Amen, Amen". It's very cute!
He also pays very close attention to how he pronounces things, he used to call Kyle "Ki" and he was happy with that, but not any more, now he says "Kyyo" (the L sound is difficult). It's still really cute.
Here is an example of my daily conversation with Cooper:
Me: Yes, dear
Can't help but love it!!
