Sleep issues?

Anyone else’s 14 month old having issues sleeping? My husband just left for 3.5 months and my son is not taking kindly to it. He now doesn’t sleep, like even during the day he only takes 1 nap. I am so exhausted and I’m pregnant 😭 I just spent the last 2 hours trying to calm him down. I ended up having to give him a bath, make him a sand which, give him eye drops (he has pink eye), and give him Tylenol in order to get him to lay down! Please tell me someone else is having this issue! 😭
