@miranda941, Yeah teething can cause them to sleep more, have diarrhea, have a low grade fever, and extremely fussy. The first few days were absolute hell. I was losing my mind bc my son was screaming non stop then I would give him Tylenol and he would sleep but as soon as the meds wore off he was screaming again and I just felt so bad bc I couldn't make him feel better.
@miranda941, it could b a growth spurt or the beginning of teething. My son turned 3 months on July 28th and a couple days before he was sleeping way more than usual. And I think he was double wammied with a growth spurt and teething.
