Shorter sleep periods during the night? Check.
Inconsolable wailing? Check.
Low-grade fever? Check.
Chewing on bottle nipple instead of sucking? Yep.
Signs of actual teeth? Nada.
So the little guy is 11 weeks old today, which is too young to be teething, really, but he was in a foul mood almost all day. Didn't want to nap, slept less than an hour between 6 a.m. and 6 p.m. It could've been gas causing his discomfort, but his fussing was a different kind of crying, a piercing wail that I've only heard once before, when he received his first round of vaccinations.
Whatever it is, my heart goes out to the poor little dude.
