Unless you're a maths genius you'll never get the percentages! It's a learning curve - you throw a bit of that in, and a touch of that and offer a bowl of this! You will find the happy medium yourself. You will see what your baby eats and doesn't eat and know to up the amounts (apart from the seed as he/she will definitely scoff that first!!). Harvey loves broccoli and spinach and eats it all up - so I give him more. He'll then eat so many pellets and then eat a bit seed. You'll find the happy medium - relax, don't worry!!!
