Water Misting  spray bottle 
Water is the key to all living things  ! And a small chameleon who's weight is less than “one gram” is in need of water  three times per day . Knowing how very little babies weigh  is important allowing you to realize the importance of misting for water consumption . Tap water left standing over night in a open container is just fine to use . (Do not add bleach to the water thinking you are helping your chameleon .) 
 Misting one side of the container if using a solid walled container is advisable also if using a screen cage   you should see the chameleon advance to drink . This can be one reason why you should not mist directly on the chameleon  It can cause them to retreat form drinking . Your are no doubt going to get water on the baby . It’s OK and for many it’s is helpful to do so . But also it’s a from of harassing them so do so with caution . Room temperature water is best . It is true in the wild the water temp is a bit cooler than the air temperature. But nowhere close to an ice cubes  temperature.  Ice cubes allowed to melt providing water is  not a good means of watering a baby chameleon . 
 We can debate over the type of spray to be used . But as long as water is supplied and the animal is drinking you have it correct . Atomizer type spray bottles are fairly common all over the world.  Ideally a small green house mister could be used  on a automatic  timer as long as you allow for the water to drain from the container. 

Feeder insects 0 to 4 week chameleon babies 
 3 to 4  weeks before you expect to hatch babies you should set up your drosophilia  cultures .  If you have to toss some away then you are doing it correctly ! Don’t worry , when 20 babies are eating your drosophilia will disappear  How many cultures per baby ! Depends on the culture size . And how long do you keep feeding them these small flies ? Depending on the species 3 to 5 weeks. If you have a smaller species of chameleon you will continue to use them as needed. You will know just buy looking at the growth of the baby .Babies   double in size rapidly . Usually within 30 days baby chameleon’s  will out grow the need for drosophilia .Then you will not need to use flies crickets will fill in the gap nicely.. 
As these animals grow try to remember that a varied diet is a good thing for the health of your animal  at 5 weeks small wax worms or if you are lucky enough to have available to you baby  super worms that have shed their exoskeleton you can feed these sparingly. 

D. melanogaster. life cycle is 3-5 days in optimum conditions, 80-85 degrees F. 
D. hydei. life cycle takes almost 30 days in optimum conditions, 80-85 degrees F. 

 Culture size can be tricky . How large a culture should you have to feed 10 baby chameleons daily 2 to 3 times per day? How many of them ? The larger the culture is in diameter the more insects will be produced. As long as you supply a larger number of adult FF to deposit eggs in the medium .  10 babies you need 3 to 5 cultures (3inch base size) weekly up and producing FF before your babies  hatch!  If it sounds a little tricky it really is not to hard to do .If you are not certain about raising from scratch  you can always purchase FF from insect suppliers . 
D. melangaster are very easy to culture D hydei are a little harder  for a beginner . So start with the easy one first . 
The melanogaster are tiny but make up for their  small size by prolific breeding .Hydei are a little larger take longer to produce . Depending on the amount of time you have to commit to raising flies one or the other will work. 
Pinhead crickets explained  as they relate to baby chameleons .. Pinheads are one week old crickets  commercial cricket breeders will supply you with these small ones as long as you ask them to . But make no mistake about ! You must explain to the cricket supplier what you need . Some will refer to these as dust sized, one day old, just hatch, ant sized . You need to get your point across to them by explaining exactly what you need ! Your needs for these very small crickets will only be 10 to 20 days . These baby crickets will grow quickly ! 
  You want to raise or purchase ant sized crickets for your baby chameleons  directly out of the egg. For the first two weeks meals . Try not to dump to many into the container this can cause a baby to become confused  unable to decide  which one to eat ! It happens … Some will go directly to flies because of the movement of the flies is different than the crickets . Some will go to crickets . 
FF and crickets mixed together  Yes you can mix them . FF will travel all over you cage  and be eaten . Crickets will be eaten from a cup if you provide or  broadcast them into you cage . 
Broadcasting crickets this simply means allowing them to free roam in the cage . It allows the babies to hunt the insects a perfectly natural instinct. Supplying a small amount of cricket food inside the chameleon cage can be a good thing also allowing those uneaten crickets to a food source other than the baby chameleon . Yes ! Baby crickets will bite baby chameleons if left in large numbers inside of your chameleons container . 
Basking  The amount of time allowed for basking can vary greatly. But all babies need to bask  allowing them to digest properly . You will recognize basking  when your babies turn their bodies  leaning  toward the sun or artificial lighting and changes color to darken themselves thus regulating body temperature . If you have a group of babies in a screen cage or a solid wall container . You  will see the babies begin to move and taking cover under leaves retreating to cooler places. That is the time to remove them from the high temperatures. Allowing  them to become cooled to room temperatures below basking spot temperature Usually this happens within 10 minutes . Basking  can occur three time daily during the babies first few weeks . Water can be supplied after basking .
