First off YOU NEED TO STAY THE HELL OFF OF YOUR WIFE!

J/K
Seriously, though my girls are 16, 18 and 20 months apart....I KNOW HOW DRAINING THIS IS.
You MUST try and get more sleep. PERIOD
Try and eat a balanced diet. No magic, just eat clean unprocessed foods, oatmeal, veggies, fruits, whole grain bread and pastas, good protein sources and be sure to get fat also (FAT IS NOT EVIL). Eat 4/5 smaller more frequent meals, drink LOTS of water.
Since I put serious physical demands on my body and my diet is limited often as I stay between 12/14%bf most of the time (done bulking) I also take a multimineral vitamin supp, Vitamin E, Calcium and LOTS of Vitamin C (C is water soluble so you can't OD on it).
Start off slowly (weight resistance training 4 days per week is plenty...I do not train more than 5 EVER). Cardio 3 times p/week at 20min a clip is more than adequate for cardio vascular health...but even w/this start off slowly and work up to it. You may feel that 10/15 is a lot at first, but you will be amazed at how quickly you will progress.
Remember though, cardio is secondary to weight resistance training. Your primary focus should be to build lean mass; more lean mass - the stronger you will be, the better you will feel, the faster your metabolism, the more effectively you will burn fat.
And THROW OUT YOUR SCALE! Use polaroids and a tape measure to more accurately guage your progress. I am 5'3 1/2" at 124# 11% bf......size 2/4. I used to be 116# at 12%bf size 2. Before that 108# soaking wet, size DOUBLE ZERO - YUCK.
Visit the women's and diet board for more specific info if you need.
I have posted a sample of the diet that I follow while leaning. I would not recomment this just yet, however. You can basically follow it...only ADD the amount and type complex carbs, also add some simple carbs (ie fruit, etc)
Good luck! And don't despair...whatever your goal is - it CAN BE REACHED. Don't let ANYBODY EVER TELL YOU ANY DIFFERENT!
