3 year older wake up at dark, getting up course too rash?

I have a toddler that will be 3 in September, and a 7 week old tot with severe acid reflux and she's just getting over a double ear infection, so Im already tired... The 3 year old's bedtime is 7pm and she usually sleeps till 7am, but I am trying to enforce nap again since she is so tired 3 hours after getting up.
For the last 3 nights she has fought going to sleep till 8-9pm, wake up screaming mad several times at night, then wishes out of bed at 5:30-6. This is a VERY stubborn and spirited toddler. Per doctors orders I lock her in her room to fall asleep, but that doesnt penny-pinching I can just fall asleep if she decides to cry, yell and kick the door.
Im really truly not trying to whine, please understand my girls are my life span. Everything I do is for them. Last night I didnt even have a chance to put away dinner, between the baby's reflux and the toddler fighting bedtime so bad. I only get a chance to sleep between 1-6, with the baby wake twice during that time. The baby of course is asleep now, but I cant sleep when my toddler is up.
Bottom stripe: I cant take care of my girls if I dont take keeping of myself, Im getting no sleep and usually all I eat is a bowl of cereal. I know I shouldnt expect 8 hours, but Id say Im getting in the region of 3 hours every 24 hours.
My husband is military and is not here, my parents are elderly and ill, and I have NO other help so please dont suggest asking friends or relatives for assistance, trust me I wish I could.
Any ideas?
You lock your daughter in her room? really, what is that going to solve? And what dr. would direction that? Get yourself a new dr.

You messed up her sleeping routine by FORCING her to take a nap during the morning. I wish my almost 3 year old would nap, but she doesn't most days, but will somedays, but i don't force her to. She go to be at 8 and wakes up anywhere between 530 and 7, latley it's been around 6.

Ya, i hate it, but i to be sure not going to screw around with her schedual. I am lucky she does sleep through the night now. As for my son, i wake up one once or twice with him. So i know what exhaustion is, but i wouldn't ever think going on for locking my daughter up in her room.

I suggest, let her nap when when she chooses too and product her bedtime at 8 instead of 7.
When my daughter was 3, she slept with me. I remember one night, I get up to go to the bathroom, and I was only gone a minute but as soon as I started to pee, I hear her crying. Because she woke up while I was gone and she was scared, because I wasn't here.
Answers:    I totally feel for you, my son will be 3 contained by November and I am 34 weeks pregnant. My husband is also in the military. I totally understand because my son has just this minute started this thing where he will wake up after two hours of sleeping. I usually approaching for him to go to bed around 8 to 8:30 at night so he can wake up around 7:30 surrounded by the morning. He usually takes a nap around 12:30. For some reason though out of nowhere he started wake up at like 10 or 11 at night and not wanting to go to sleep until 2 or 3 within the morning. I am tired being in my third trimester and I really hope he doesn't do this once I have the tot. I think you should let her take nap because she might be really sleepy and not sleeping enough is making her hyper. I notice that in my son. Hopefully she will give somebody a lift a nap when the baby naps so you can attain some rest as well. I know it's hard not having serve because we are stationed overseas and don't really know anyone. Maybe your daughter is interested in the baby and wants to know what's going on. Sorry this is so long. Not really sure if I help.
Time for your kids to get on impossible to tell apart schedule. I'm sure you already prop your baby up when she sleeps but if you dont, try it. it soothes the reflux. My almost 5 year old still take naps so i dont think having them give somebody a lift a nap is a bad thing. instead of locking the door for your toddler, try using a babygate. you enjoy to sleep when your kids sleep and i'm sure you have been told that a thousand times but literally do it. i used to the laundry and other household chores until i realized how DEAD tired i be. get a nice bedtime routine for the toddler. at night try putting on a disney movie your toddler can fall asleep too and instead of calling it powernap try sayng "QUIET TIME" i told my son that he didnt have to sleep and he could read or do whatever he wanted at QUIET TIME so long as he stayed contained by his bed and was quiet, 99% of the time, he fell asleep. i would also advise putting toddler to bed at 8:30. i know its unyielding, but try to keep the baby up as long as she can stand it so you can try to even up their schedules. My husband told me that babies cant be put on schedule (when i had my daughter) so i was determined to prove him wrong and YOU CAN put a baby on a programme.i would also try to hire someone to take care of the kids for 2 hours a day while you siesta. you'd still be home incase anything happened but you would be able to sleep.
Man, I wish I could help you I raised eleven of my siblings :D Uhm try to run to the park with him and make him run around or go swimming or even hold a nice bath and settle down with a movie of his choice.


Goodluck
