Erm, I've only ever had Molly weighed twice. I know she's putting on weight as she's really chunky and I weigh her on my own scales at home (not quite the same I know).
I don't know why, but after her 6 week check up with the HV, she hasn't been weighed or even looked at since. (Apart from having her 2 month and 3 month jabs of course). Maybe I should get her looked over just to be on the safe side?
