My son just turned eleven months old and the past couple of Weeks he's been excessively whiney and excessively sleeping, he's not running a fever or anything, I thought maybe it was his teeth.but I'm not sure, is it bad that he's excessively sleeping, everyone says he's just growing but like today hes only been awake maybe 5 or 6 hours total its 7:00 pm and he's asleep again already
