Mackenzie is 4 1/2 months and weighs 2lbs 3oz...I free feed her too..she only gets dry food...except in the mornings....I give her a little bit of her dry food mixed with about a half teaspoon of cottage cheese, she loves it. Like I said I free feed through out the day, but what I put in her bowl I do measure, so what she is eating amounts to almost a half a cup each day.
