Exhaustion

So I guess I've been on a bit of a hiatus. It's not that I've forgotten about my blog, just that I have been too exhausted to write in it.
Oliver has been sick for the past 3 weeks. I wasn't sure what was wrong. He seems fine for much of the day, but every night is up coughing and having trouble breathing. I finally took him to the doctor's on Thursday, and it turns out he has bronchitis. The poor little guy is miserable. I am up for several hours every night with him, as well as ALL day (as he has not been napping since he got sick). He has a humidifier in his room, and I also take him outside into the cool air around 3am every night to help him breathe. He also has an inhaler now. I have been incredibly patient with him, never getting frustrated when I'm up for the majority of the night with him. Unfortunately, Makenna has been getting the brunt of my moodiness. I am terribly ashamed to admit I have been snapping at her left, right, and centre. I know it's not her fault that I'm not getting any sleep. Oliver is extremely demanding and clings to me like I am air, so he ends up getting the majority of my attention. I have not been spending the quality time with Makenna that she needs. In turn she acts out, and instead of me being compassionate towards her, I get her in trouble. I feel really guilty about how much she has been getting in trouble lately. I don't know how to solve the problem. It would be nice if my husband could give her the attention that she is lacking from me, but he works really long hours and goes to school two nights a week, plus Saturdays. He's just as exhausted as I am.
I just hope Oliver gets better soon... for his sake, mine, and Makenna's.
