Sleeping Regression

Little Garrett has been going down to sleep so easily for a long time. About a month or so. However, just recently, he has been crying and crying when it's time to go down for sleep. He used to suck his thumb to calm himself down and go to sleep, but he's not doing that anymore. It's weird.

So now, we are back to timing him when we put him down. I go in after 3 minutes, then 5 minutes, then he's usually asleep. But this pattern seems to be getting worse instead of better. He woke up to eat around 11pm last night and refused to go back to sleep when he was done. Usually, he would go back down sucking his thumb and sleep so easily.

I wonder if he's going through a growth spurt or some other weird thing that is keeping him uncomfortable. But why stopping the thumb sucking? You know, I can handle the crying, it doesn't bother me as much as it used to. However, I just feel sorry for my little guy who seems to be suffering.
