Aww! He looks like a little tiny scoot in your avitar! very cute! Hmm, as for feeding more, I would slowly progress him up a size as his girth grows, and then after he's been eating adult mice for a while (oh,.. say 2 months, but it really depends on the growth rate of your snake) you can feed him a second adult mouse if you wise. I got my first BP, which was a May '06 hatchling, for christmas last year, and at 7-8 ish months old I was feeding her 2 adult mice every week, then I switched to rat pups every week, and now a year and a half later i'm feeding her small adult rats every 7-10 days. It's really a judgement call on your part.
