My boy knows how to turn and can sit and play by himself now. But after a while, he will shout for someone to carry him or accompany him.
He got 4 teeth already and other teeth seem to be coming out also so he always bites eveything he get and a little bit inpatient and shouting "ah .. ah..." always.
He seldom cries, he only "ah .. ah..." He takes pump milk 3 - 4 times (5oz) in day time and then I feed him after work (7:30pm, 12am, 3am, 7am). Now I feed him the Babynat cereal and apple puree.
