Imo, they should be seperated from either parent. Cricks are high in phosphorus and a poor feeder especially for neonates. Would recomend a petstore melongaster culture fo the immediate and immediatley ordering a " producing hydei culture." Probably a good time to get a mantis egg case if you can. If you can find one locally at a garden shop,You can probably get it to hatch in less than 5-10 days@ 88* might also be a good time to start attracting wild ffs. I would avoid any supps other than plain cal for at least a few weeks. Jmo
Ps hope it goes well, can be an exciting time.
Would also like to say not to let the event overshadow care of the mom. Serious metabolic issues often follow a xanth birth and she will need extra care and observation for the next month. Imo, feed and supp sparingly, hydrate heavily. Jmo
