My first baby pumilio had SLS (spindly leg syndrome.) Since then, the same pair has raised two more healthy fellows, which I separated once they were out and about and feeding well. I don't know how long a pair will put up with an offspring in their territory, however. They may be safe enough with their parents until they are sexually mature.
Although feeding springtails seems to be the recommended food for new pumilios, mine all seem to take small wingless fruit flies as soon as they begin to hop about. Spring tails are rather primitive insects that are a decent source of calcium and vitamins without needing to be dusted. This may be of some importance when feeding the new babies, aside from being definitely small enough for them to capture and eat.
Just some observations, if this helps.
