They are cuties!
I don't usually start foods until the 3rd day or so... more like the 5th or 7th, depending on hatchling. Get a little food on your finger tip and let them smell it/lick it off. I offer pinheads at day 7... 2 or 3, usually. I've never put a water dish in a hatchling's viv.. I just mist and keep an eye on their first couple of sheds... remove any lingering pieces to avoid lost toes or tail tip. You may even have to set them up in a "humidity cup" if the shed persists.
Baby B should be fine... just a little late to explore maybe.
