As far as hides for baby bp's I just love the ones I get from the good old dollar store. Three small dark blue cereal bowls for all of a dollar, we melt a hole in the "roof" and bingo...nice sized baby bp hides that they seem to love, easy for me to clean and when they grow out of them I just disinfect them, pop them into a big ziploc bag and keep them for the next babies to come along. Here's one of our 06's tucked up happy in her hide.
They are just now starting to grow out of these hides so will move up to the next size up blue cereal bowl (it's pretty much a regular size bowl, this one pictured is smaller than a full sized cereal bowl).
