Ace and his fussyness

Poor little Ace has just not been having the best days at daycare. He's like a roller coaster. One day will be perfect and then the next day a complete cry fest. Just saddens me when Vicky tells me he's been crying all day. Most of the time he'll cry himself to sleep if he's being super fussy with her. Just hate the fact that he has to be constantly put to bed if he's having a bad day. I know what it's like when he's super fussy and I too put him to bed and he'll fuss himself to sleep. Just wish we knew if he was in pain or getting teeth. I'm tired of always blaming his fussyness on his teeth. He so far hasn't had any pop through nor does it look like any is to pop through. Guess this faze shall too pass but it's so hard to find out that he's been so fussy all day long. Poor guy.....
