DS spent the past week with a cold and hasn't been sleeping well. Last night was really bad - up every 2 hours, bf back to sleep , up for the day at 7am. He had a long nap (for him) from 9:30 - almost 11am when I had to wake him up for an audiologist appointment (all is well hearing-wise). We came home, he was okay, not great. We went to the park and he had another nap from about 2:30pm - almost 4pm when I thought I'd better rouse him so he'll sleep tonight. He's been sleepy ever since. No temp that I can tell (underarm thermometer read 37.1), regular nappies. Just really tired. Could he be this tired from not sleeping well last night and earlier in the week?
