I have 3 PBPs, one i 6 weeks, one 6 mos. and one is 7 1/2 mos. How much should I feed them? Different sites say different things. One says feed free-choice until about a year, while another says 2 cups ----per day? per feeding? and the people I got the 7 1/2 mos. old from said 1/2 cup of feed twice a day. I have been feeding the baby as much as he wants, and the girls about 1-2 cups twice a day each.
