Hello, welcome, and congratulations!
I'm a bit rubbish with all the weight business....but I do know about weiners (or winkies, as I call them !!!)
I must admit - Harry has never had a 'leaky one'....but then again I always dry his feet and his winkie when he comes in from the garden....and I also wipe his bottom, just in case...
Enjoy every moment of your new little one! Sally + Harry
