Molly's Mum, I presume you're already familiar with what to feed Molly and how many times a day puppies need to be fed....
Also I think they need quite a bit of stimulation as dogs on their own get bored easily and then want to chew things up... have you thought about something like a Puppy Kong to keep her amused for a while, now and again?
Puppy Toys & Puppy Chew Toys - KONG Safety Information
Our two sister Bassets have two toyboxes with chew toys, tug toys, furry balls etc in the kitchen and in the hall so they have things to amuse themselves with when they feel like it. I don't know what it's like where you live, but most pet shops near me have balls for dogs to play with that have a string attached, which is handy because of safety for one thing!
My neighbour told me ages ago that one time when they were out with their dog, a man had his Boxer dog out too and he was throwing a ball up in the air for his dog to catch and the dog caught it in his mouth and choked on it, and collapsed and died, whereas had there been a string on it, he could have got it out so I have always been very wary of balls that fit in a dog's mouth, unless it has string on it!
