Welcome to Frog Forum! You can start them up with crickets that are the size of distance between eyes. Can also use night crawlers; if real tiny can cut worms up to size it can take. I dust my Pacman food with a Ca supplement every other feeding and a multi-vitamin one once a week (on weekends). If baby imagine it's less than 3 in. and can feed daily.
Also, lots of good information here: http://www.frogforum.net/content/pac...-breeding-170/ Good luck!
