baby owl got her 2-month vaccinations yesterday. she handled them pretty well (cried a bit, of course, but was fine after some mommy snuggles). she didn't seem sleepy or feverish at all last night. today she doesn't seem to have much of a fever (she is a little warm, but the thermometer says she's fine), but she has been sleeping ALL. DAY. LONG. i've had to wake her up to feed her, and then she conks right back out. is this normal? did your little ones sleep a lot after their 2-month vaccinations? if so, how long did it last?
