Hello ladies,
Feeling a little desperate here. I'm at my wits end after 2 weeks of 15 month old illness and mama being sick with DH out of town

PLEASE HELP!!!!
Here's the run down...
N is just over 15 months old and pre-illness was sleeping 1 nap a day (about 1h10-20 LSN) and STTN 11 hrs. 2 weeks ago everything started with a fever. Had a fever for 7 days, after 3 days had ear infections in both ears, super congested and a nasty nasty cough....oh, and don't let me forget that he started getting all 4 of his molars. I (of course) caught this about a week ago and all of this has been absolutely draining (especially with DH not here).
Regardless of everything going on, I could still put him down awake for a nap and BT with no problems. Amazing! Only problem I was having....is because he's such a poor napper, he doesn't sleep longer when he's sick and needs it...he sleeps less. Awesome. So because he's so exhausted, he was literally falling asleep after being awake for 3 - 4 hours. N has NEVER randomly fallen asleep outside of his room for nap (very alert, needs total darkness and white noise)....however passed out cold watching tv 3 hours after waking....that's how I knew this was bad. So...we ended up with 2 nap days.
Now, he's almost himself again and can definitely handle being awake for longer so my goal was to start getting back on track. Now he's suddenly screaming bloody murder when I go to put him down for a nap and BT. He's been super clingy through this entire illness....like crawling all over me like he just couldn't get close enough to me. He also ended up sleeping on me (a habit that took months and months to get over) some morning after incredibly EW's and for some catnaps.
At BT I usually put him in the crib and then leave the room to get the bath ready. He usually plays and roles around when I do this.....but now as soon as I go to put him down...SCREAMING. He screams the entire time I'm getting things ready. I try to pop in and out and talk so he can hear me....always reassuring that I'm still here.
At BT He's screaming once I put down and leave the room....but stops just a couple minutes later. However, naps have become my BIGGEST problem. I've had to make multiple attempts with him just screaming before finally calming down and going to sleep. This nap now lasts anywhere from 25 - 40 minutes because he's so OT by the time he falls asleep. Because he's so easily distracted and needs his darkness.....the only type of sleep training that has worked in the past has been for me to leave him alone and let him figure it out. I've tried everything because I hate leaving him to cry....but any interference from me makes things a thousand times worse. The problem now is, I'm worried about this just adding to the SA he seems to be experiencing. Do you think it sounds like SA?
I don't know what to do for him now....how to get him napping again and how do I get rid of the SA???
I'm so exhausted from all of this....I just need things to start heading up. I'm still so sick....and haven't got any sleep.
PLEASE HELP!
Sorry for the long post....just trying to cover everything.
