So sorry for your loss! Poor thing definitely calcium is a must. A very smart vet told me that crickets are made of phosphorus, which blocks calcium obsorbtion, therefore you need non phosphorus calcium. One I have been using for years T-Rex 2:0 Calcium - No Phosphorus - Free Shipping. Best stuff on earth. I only give my frog crickets, I don't bother with the other stuff and he's been around a very long time! Good luck with your baby!
