I posted a lot in Napoleon's thread in the Infectious Disease section about my struggle to administer foul tasting medicine and syringe feed formula mixed with an assortment of different bearded dragon friendly foods. Honestly, she loves it. I start with a dollop on the middle tip of her snout over her lips, and Napoleon usually starts licking. Sometimes I make "nom nom nom" smacking sounds... Yeah I'm a dork. On occasion, it takes her a bit (several minutes or longer) to start licking, when she does, start squeezing a bit more onto her lip area (never into the front inside her mouth, they can aspirate). The most important thing is to relax! I was so nervous the first 2 times that I was shaking uncontrollably... This really doesn't help (it's a miracle that Napoleon didn't have shaken beardie syndrome)! If I learned to syringe feed a baby bearded dragon... Anyone can! You'll sort out quickly what works for your dragon, how thick she likes the formula, and how she wants to be held or not held while she syringe eats.
Best wishes,
Shara and sleeping Napoleon (she just went to sleep!)
