Oh thanks for those pictures! I think we are onto something here !
The coil/compact isn't any good, you'll want to change that out for a tube reptisun 10.0

Just get two of them, since you are planning on separating soon.
Oh and instead of that infrared, change that out with a house hold bright White light
Also, that 10 gal is awfully small to try to maintain temperature gradients. As well as housing two month to 5 week old babies.
I would also remove the water dish, as that will bring up the humidity quite a bit in such a small enclosure.
For baths, water up to shoulders, temps 90-100*F for around 15-20 minutes. Use either your hand or a wash cloth for traction. Never leave alone, while bathing .
I didn't see how you were measuring those temps, by the way. Are you using
a temp gun ? I don't see any on the walls of the tank. Nor do I see a probe.
So I am thinking that since things are out of sorts, this would indeed cause such a small baby to not do well.
Hope this helps out !
