Beyond exhausted

Tonight is just taking the max energy it can. I am sleep training my son to fall asleep on his own using a very gentle method. He already sleeps through the night and we contact nap during the day but falling asleep on his own is not a skill he has developed yet. It took my son an hour to fall asleep on his own with constant checking and reassuring he was safe and loved. Then I waited a bit extra to ensure he was in a deep enough sleep for me to sleep because the crib is next to my side of the bed. 2 hours after I finally sleep my 2 yr old daughter wakes screaming and I spend half an hour trying to figure that out. Turns out she woke up cold and was unhappy. So extra blankets (even grabbed her dad's special extra large fuzzy blanket), and a few episodes on her favorite show and she fell back asleep no problem. I too fell asleep on her floor (because she refuses her toddler bed for some reason but it is an option). An hour or two later my son's cries wake me. I go back in my room and grab him and feed until he is almost asleep, burp and lay him back in his own crib. Hopefully that was the late wake up of the night because my husband wakes up in an hour and a half and there is no way I can sleep through that.

What makes this extra exhausting is my husband is a school bus driver he will be gone before the kids wake up, during his normal break he has errands so there will be no relief for me until the kids either go to sleep or are ready for bed. After work he has a play rehearsal and I resent him for it. On a good day he is home 2-3 hours for lunch and home by 6. Now he doesn't get back until 9pm or later 3 days a week. Plus I top of 2 very young kids I am currently 14 weeks pregnant.
