That's exactly what I meant. For me, since I'm trying to get a girl up to breeding weight by next fall, I feed her on a 4 day schedule and I'm about to bounce her up to a 6 or 7 day schedule. But for you, feeding every 7 days is just fine!
One thing to watch out for is feeding an underweight baby too fast. You don't want them to regurgitate. Start off small and once a week for at least a month or two. Then you can bump up the size and the frequency of meals.
