I've had my girl Lucie for 3 months. The breeder didn't tell me how old she was when I got her, but I'm estimating about a month or so. So my best guess is that she's about 4 months old. I usually weigh her once a week, the day before feeding day. She's had pretty steady growth for the last few weeks. But when I weighed her this week she had gone up nearly 60g from the week prior. From 270-330. Double what she normally gains in one weeks time.

Is this normal for a Ball her age? I know any major weight fluctuations, up or down, can be problematic. But I'm not entirely sure what constitutes a "major" shift. Especially given she's still really young and growing.
