"Scha," "S..h..it," and other three syllable words

While Ivan seems to have forgotten the "scha" he learned from me a few weeks ago, he now pronounce another word, the way I had properly pronounce "scha." He inserts sh for every s.

S words that get a sh are: bus, mess, and sit, which he says rather quite often. It's almost embarrasing.

He's also mastered three syllable words, such as "cipele," Croatian for shoes, "nonine," which should really be "novine," which is Croatian for newspaper, and "mamine," which is a Croatian possesive form for mom's.

He's also started to differentiate languages. Yesterday, he insisted on going "dole" as I was standing on the top of the stairs with him, while with Andy he insisted on going "outside." He also says cipele to me and shoes to Andy.

Also, last night, he went to bed early. When I got home at 7, he was already in quiet in bed, but not asleep.

My arrival roused him up. He insisted on going into our bedroom to look and point for "fuk in." He looked under the bed, he pointed to a corner of the bedroom. It was as if he was desperately trying to explain or communicate something to us. We couldn't figure out what he was saying nor what he wanted. Instead of kept looking at it each other, wondering whether he's saying what the word sounded like, and wondering when he could've heard that word. We still have no clue what he was trying to say.

Eventually he got tired of trying to "fuk in." He climbed up on the bed, leaned against the head rail and looked around all content, as if he owns the place. It was really weird.

Then he insiste on going "dole." Once downstairs, he insisted on "cipele" and "outside." Andy took him out to see what he wanted. Nothing. He just didn't want to go to sleep. Yet he was so overly tired that he need to go to sleep. Within 15 minutes, he was out like a light.
