In talking to Dad about it, Mom (baby is a Momma's boy, he's been home with her all year & still cries when she leaves the room at home)...anyhow turns out Mom is out of town (has been since Friday) and he feels that baby is out of sorts over that too as this is her first time leaving him. Poor little guy; tough week. That and he's teething (prob why he's not so crazy about eating either). By about 2pm it's like a switch went off in a millisecond...he went from screeching to smiling, laughing, playing (still stayed within reach & cried if I went o get up off the floor)...then by 3pm he was crawling all over the playroom exploring as the rest of the group sat with me for storytime. Yay!! I've asked them if they could possibly leave him 2 more consecutive days this week to keep the positive transition momentum going. Thanks again everyone.
