This time last year, Nick was starting to but 2 & 3 word phrases together. But, the words were one syllable or one syllable of a longer word and the phrases were often echos. Now, he's putting together real sentences with multiple syllable words. The other night in the bath he said "Go way, no wash my hair." He's also started to answer questions about things that happened. We're not quite to being able to ask him about his day but, occasionally, he'll tell us about something big that happened at school. And he actually answered a question in circle time at school.
Last year we were working on potty training but not seeing much success. Now, he mostly goes on demand and stays dry as long as we put him on the potty. Now, he can undress himself. The other day he pulled down his pants & pullup and peed on the potty all his own.
Self help skills are coming along, he has mastered a fork and spoon and eats cereal with a minimum of mess. He drinks from an open cup without spilling. Undresses himself, of course, I often find him naked in the bath tub! He knows to cover his mouth when he coughs and mostly to use tissues to wipe his nose.
When you have a child with delays, it's hard to see progress. Perhaps we need to take a longer view more often.
