The boys started preschool last week. Eldest is in a 4-year-old class again (he was young for his class last year because there wasn't any room in the 3-year-old class when we switched preschools), while Littlest is began 2-year-old preschool.
So far, so good.
Eldest is a veteran of this class, so I wasn't worried about him, other than wondering if he'd be jealous we'd be dropping Littlest off then leaving (both classes are in the same room). But he's been fine. I wasn't sure about Littlest, however, but he's adapted quickly. He's used to playing in this room, so he feels right at home -- if anything, he always wants to play and doesn't want to sit down for circle time or snack. Other kids are having separation anxiety, but not Littlest, who is so low-maintenance that as long as he's not bored, he's fine.
Eldest goes to school Monday, Wednesday and Thursday, Littlest goes Tuesday and Friday. The routine is back, and it's busy.
