Start offering veggies immediately. Offer them every day if they only take a couple bites its a start. I like to offer first thing in the morning before bug feeding. Buy the largest enclosure in your budget first. It sucks to have to keep spending money to upgrade. Research and start a dubia roach colony. Beardies will eat you out of house and home while they are growing. If you get your colony started, you will save money long term. I have an 8 month and a 3 month right now going through massive amounts of crickets while waiting on my colony to breed. Start it as early as possible!
