The most important thing for you to do right now is nothing.....Don't get your mates around to check them out, don't fuss around them yourself, don't throw food in for the mother or young and don't worry about anything.............you can do all those things once they've left the mother
The mother doesn't really need any food right now and besides she can easily go a week or 2 without. The young also don't need any food and won't eat until anything from a couple of days to a week and a half after they've moulted to 2i. They'll get the moisture they need from being on their mothers back.
You can separate them from the mother when they have moulted to 2i and left the mothers back. This can take all in all, 2 or 3 weeks.
