My just turned one DD seems to be sleeping a lot. Yesterday she had a three hour nap in the afternoon then slept for 13.5 hours last night and has been asleep again this afternoon for 3.5 hours. She had her immunisations about 10 days ago, she seems well in herself she's got a snotty nose and had a cough which is better now. She doesn't seem to be in discomfort or pain. She went through a few days of eating loads too but didn't eat as much yesterday or today so far. She hasn't got a temperature she's just a bit whiney but that seems more because she is tired. Is this normal? I'm a bit worried about her.
