So how is Nicholas doing these days with his speech? He's 4 1/2 and with the exception of mixing up his pronouns (she/her/hers and he/him/his) he is doing very well. I would describe his clarity with strangers at about 3 1/2 though.
Jonathon is moving along well. He picks up poor grammar from his brother and the two of them use several of the same mispronunciations. For example:
Bubblefly: A flying insect with often colorful wings.
Catterputer: Those little crawly bugs that turn into bubbleflies.
Munty: aka Something.
If I here any more, I'll add them in. They are getting bigger so the cute words are being edged out by proper words, which is a sad thing to see.
