Hi, your baby is beautiful, loved the pics you took. I'm Deb, so Mike (Zeus) pm'd me to check your thread. You're doing great so far, I love the fact that your baby loves his/her greens and she/he looks wonderful, great little belly happening. Yes, you need to put calcium on her bugs or her veggies, whichever works better for you but only once a day for 5x/wk, then you need to get vit/min (I used Flukers, as they didn't like the repcal) and that's once a day 2x/wk. This is just because you have a baby, they use less calcium/vits as they get older, but for now that's the amount you need to use.
For heat at night I never had to use heat at night because my living room heat was always on & it never got under 65F. If it did I did use heat lamps but I always covered by babies (I've only ever had 3, the others were adopted as adults) with a facecloth, as they can't have any light on or they won't get a good night sleep. If you want, you can get a ceramic heat emitter, it gives off heat but not light. You want to get a low wattage one, 60W, as you have a small tank & you don't want the tank to heat up over 70F at night, they need the cooler temps to sleep.
Heating pads are for geckos, not dragons, as dragons feel heat from above, they have a "third eye" on their foreheads & that's how they guage heats. For the basking light, I've always used regular household lights. The clear ones are the best ones, if you can find them, and they're alot less expensive than the flood lights or others like that. They also are easy to replace, as you can buy them cheap at Lowe's or Walmart. The digital probe Mike was talking about is inexpensive at Walmart $12 I think, I have a temp gun that I use, it's great & give very accurate temps. You want to have the basking spot on for about 45 min to check the temps, but your baby can still sit there for that time & then you can move her to check the temps. Should be between 105-110 for good digestion, even though it's probably right, as those other ones are usually off by 20F or so. It's expensive to get the right stuff at the beginning. I like the using of velcro to set up the reptisun 10.0 tube, but if that's not possible you can get a good fixture from a hardware store. The Reptisun 10.0 are good for 6 mo, so you'll have to make sure you can replace them regularly. That's the most expensive cost, is the
UVB light. If you have a credit card you can order them from

The other thing is to check this great nutrition list at
http://www.beautifuldragons.com It's great & I've been using it since 2006 to find different veggies & greens to give my beardies. I live near Vancouver, BC, Canada, so not alot of good greens up hear, but found out Walmarts that have grocery sections sell collard greens, which are great greens for dragons.
I think I've covered your basic questions. Once your baby gets bigger you'll want to get her a 40 gallon breeder, or make your own. There are two sections on here to help you with enclosures. "Enclosures" and "DIY" (Do It Yourslef), you'll get great ideas from those two sights.
I'm going to include pics of my four guys, so you'll have an idea of how different adult beardies can be, hope you don't mind, I like to brag about my babies:
Leo, 5 yrs old:
Rubio (my big guy & my baby, 4 yrs old):
Lonzo (my old guy, 9 yrs old):
and Didi, my littles & most colourful guy, 6 yrs old:
Hope we see more pics of your little one, eventually, as he/she grows you'll be able to tell what sex he is.
