I know that when the time change occurred in the fall, there was a lot of lamenting about how poorly LOs adjusted. A week from Sunday we spring forward, meaning we lose an hour!
Since we were going through a time change AND traveling through three time zones in the same week, I started altering LO's sleep schedule about a week before in the fall. It really helped. I'm planning on starting this Sunday, and starting 10 minutes earlier to bed, gradually getting to the hour by next Sunday. Hopefully.
